      gianfar: Fix and cleanup Rx FCB indication · ba779711
      Claudiu Manoil 提交于
      This fixes a less obvious error on one hand, and prevents futher
      similar errors by disambiguating and optimizing RxFCB indication,
      on the other hand.
      
      The error consists in NETIF_F_HW_VLAN_TX flag being used as an
      indication of Rx FCB insertion. This happened as soon gfar_uses_fcb(),
      which despite its name indicates Rx FCB insertion, started
      incorporating is_vlan_on().
      is_vlan_on(), on the other hand, is also a misleading construct because
      we need to differentiate b/w hw VLAN extraction/VLEX (marked by VLAN_RX
      flag) and hw VLAN insertion/VLINS (VLAN_TX flag), which are different
      mechanisms using different types of FCBs.
      
      The hw spec for the RxFCB feature is as follows:
      In the case of RxBD rings, FCBs (Frame Control Block) are inserted by
      the eTSEC whenever RCTRL[PRSDEP] is set to a non-zero value. Only one
      FCB is inserted per frame (in the buffer pointed to by the RxBD with
      bit F set). TOE acceleration for receive is enabled for all rx frames
      in this case.
      
      This patch introduces priv->uses_rxfcb field to quickly signal RxFCB
      insertion in accordance with the specification above.
      
      The dependency on FSL_GIANFAR_DEV_HAS_TIMER was also eliminated as
      another source of confusion. The actual dependency is to priv->hwts_rx_en.
      Upon changing priv->hwts_rx_en via IOCTL, the gfar device is being
      restarted and on init_mac() the priv->hwts_rx_en flag determines RxFCB
      insertion, and rctrl is programmed accordingly. The patch takes care
      of this case too.
      
      Though maybe not as self documenting as the inlining version uses_fcb(),
      priv->uses_rxfcb has the main purpose to quickly signal, on the hot path,
      that the incoming frame has a *Rx* FCB block inserted which needs to be
      pulled out before passing the skb to the stack. This is a performance
      critical operation, it needs to happen fast, that's why uses_rxfcb is
      placed in the first cacheline of gfar_private.
      This is also why a cached rctrl cannot be used instead: 1) because
      we don't have 32 bits available in the first cacheline of gfar_priv
      (but only 16); 2) bit operations are expensive on the hot path.

      gianfar: Remove wrong buffer size conditioning to VLAN h/w offload · 13f228da
      Claudiu Manoil 提交于
      The controller's ref manual states clearly that when the hw Rx vlan
      offload feature is enabled, meaning that the VLEX bit from RCTRL is
      correctly enabled, then the hw performs automatic VLAN tag extraction
      and deletion from the ethernet frames. So there's no point in trying to
      increase the rx buff size when rxvlan is on, as the frame is actually
      smaller.
      And the Tx vlan hw accel feature (VLINS) has nothing to do with rx buff
      size computation.

      Claudiu Manoil 提交于
      Group run-time critical fields within the 1st cacheline (32B)
      followed by the tx|rx_queue reference arrays and the interrupt
      group instances (gfargrp), all cacheline aligned.
      
      This has several benefits. Firstly comes the performance benefit
      by having the members required by the driver's hot path re-grouped
      in the structure's first cache lines, whereas the unimportant
      members were pushed towards the end of the struct.
      Another benefit comes from eliminating a 24 byte memory hole that
      was rendering gfar_priv's 2nd cacheline useless. The default gcc
      layout of gfar_private leaves an implicit 24 byte hole after the
      errata (enum) member. This patch fixes it.
      
      The uchar bitfields were pushed towards the end of the struct
      as these are not run-time performance critical (used for init
      time operations). Because there is no other 2 byte member
      around to couple the uchar bitfields memeber with, we will
      have an addititnal 2 byte hole after the bitfields. This is
      unsignificant however, and it doesn't influence gfar_priv's
      size, because the whole structure is padded to be a 32B multiple.

      Use device pointer (dev) to simplify the code and to

      The dev pointer is required on the hot path, see gfar_new_rxbdp
      or gfar_clean_rx_ring (or xmit), and this patch makes

      gianfar: remove largely unused gfar_stats struct · 68719786
      Paul Gortmaker 提交于
      The gfar_stats struct is only used in copying out data
      via ethtool.  It is declared as the extra stats, followed
      by the rmon stats.  However, the rmon stats are never
      actually ever used in the driver; instead the rmon data
      is a u32 register read that is cast directly into the
      ethtool buf.
      
      It seems the only reason rmon is in the struct at all is
      to give the offset(s) at which it should be exported into
      the ethtool buffer.  But note gfar_stats doesn't contain
      a gfar_extra_stats as a substruct -- instead it contains
      a u64 array of equal element count.  This implicitly means
      we have two independent declarations of what gfar_extra_stats
      really is.  Rather than have this duality, we already have
      defines which give us the offset directly, and hence do not
      need the struct at all.
      
      Further, since we know the extra_stats is unconditionally
      always present, we can write it out to the ethtool buf
      1st, and then optionally write out the rmon data.  There
      is no need for two independent loops, both of which are
      simply copying out the extra_stats to buf offset zero.
      
      This also helps pave the way towards allowing the extra
      stats fields to be converted to atomic64_t values, without
      having their types directly influencing the ethtool stats
      export code (gfar_fill_stats) that expects to deal with u64.

      net: fec_mpc52xx: Read MAC address from device-tree · db98f081
      Stefan Roese 提交于
      Until now, the MPC5200 FEC ethernet driver relied upon the bootloader
      (U-Boot) to write the MAC address into the ethernet controller
      registers. The Linux driver should not rely on such a thing. So
      lets read the MAC address from the DT as it should be done here.
      
      The following priority is now used to read the MAC address:
      
      1) First, try OF node MAC address, if not present or invalid, then:
      
      2) Read from MAC address registers, if invalid, then:
      
      3) Log a warning message, and choose a random MAC address.
      
      This fixes a problem with a MPC5200 board that uses the SPL U-Boot
      version without FEC initialization before Linux booting for
      boot speedup.
      
      Additionally a status line is now be printed upon successful
      driver probing, also displaying this MAC address.

      gianfar: dont conditionally alloc Rx/Err irq structs · 7c1e7e99
      Paul Gortmaker 提交于
      Commit ee873fda
      
          "gianfar: Pack struct gfar_priv_grp into three cachelines"
      
      causes the following null dereference at driver init on sbc8548:
      
         libphy: Freescale PowerQUICC MII Bus: probed
         Unable to handle kernel paging request for data at address 0x00000000
         Faulting instruction address: 0xc01d6a38
         Oops: Kernel access of bad area, sig: 11 [#1]
         [...]
         NIP [c01d6a38] gfar_parse_group+0x228/0x280
         LR [c01d6a34] gfar_parse_group+0x224/0x280
         Call Trace:
         [ef82dd60] [c01d6a34] gfar_parse_group+0x224/0x280 (unreliable)
         [ef82dd90] [c01d73a4] gfar_probe+0x284/0xfe0
      
      The reason is that the commit also changed the allocation of the
      Rx and error handling irq structs to be skipped for !MQ_MG_MODE.
      In the !MQ_MG_MODE case, only the Tx irq struct is allocated.
      
      Digging further, we see that MQ_MG_MODE is set only if we find
      the OF compatible string "fsl,etsec2".
      
      A quick grep in the dts directory shows lots of boards that support
      Rx/Tx/Err, but without this specific compat string.  And hence they
      go after the unallocated Rx/Error structs and cause the above oops.
      
      Hence such a change can not be deployed until all the dts files
      are updated and sufficiently deployed.  Further, the optimization
      is of limited value, since the kmalloc'd struct in question has only
      a single unsigned int, and an (IFNAMSIZ + 6) sized string.
      
      Note that no changes to the freeing code are needed here, as it
      already did an unconditional free of Rx/Tx/Error gfar_irqinfo.
