      bnxt_en: New Broadcom ethernet driver. · c0c050c5
      由 Michael Chan 提交于 
      Broadcom ethernet driver for the new family of NetXtreme-C/E
ethernet devices.

v5:
  - Removed empty blank lines at end of files (noted by David Miller).
  - Moved busy poll helper functions to bnxt.h to at least make the
    .c file look less cluttered with #ifdef (noted by Stephen Hemminger).

v4:
  - Broke up 2 long message strings with "\n" (suggested by John Linville)
  - Constify an array of strings (suggested by Stephen Hemminger)
  - Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
  - Use PCI_VDEVICE() to populate pci_device_id table for more compact
    source.

v3:
  - Fixed 2 more sparse warnings.
  - Removed some unused structures in .h files.

v2:
  - Fixed all kbuild test robot reported warnings.
  - Fixed many of the checkpatch.pl errors and warnings.
  - Fixed the Kconfig description (noted by Dmitry Kravkov).

      net: bcmgenet: Fix early link interrupt enabling · 37850e37
      由 Florian Fainelli 提交于 
      Link interrupts are enabled in init_umac(), which is too early for us to
process them since we do not yet have a valid PHY device pointer. On
BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
because phydev is NULL.

Fix this by moving the link interrupts enabling in
bcmgenet_netif_start(), under a specific function:
bcmgenet_link_intr_enable() and while at it, update the comments
surrounding the code.

      net: bcmgenet: Implement RX coalescing control knobs · 4a29645b
      由 Florian Fainelli 提交于 
      Add support for the ethtool rx-frames coalescing parameter which allows
defining the number of RX interrupts per frames received. The RDMA
engine supports a configurable timeout with a resolution of
approximately 8.192 us.

We can no longer enable the BDONE/PDONE interrupts as those would
fire for each packet/buffer received, which would defeat the MBDONE
interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a
PDONE/BDONE interrupt when the threshold is set to 1.

      net: bcmgenet: Implement TX coalescing control knobs · 2f913070
      由 Florian Fainelli 提交于 
      Configuring the ethtool tx-frames property, which translates into N
packets before a TX interrupt is the simplest configuration scheme
because it requires no locking neither at the softare nor hardware
level, and is completely indepedent from the link speed. Since ethtool
does not allow per-tx queue coalescing parameters, we apply the same
setting to any transmit queue.

We can no longer enable the BDONE/PDONE interrupts as those would fire
for each packet/buffer received, which would defeat the MBDONE interrupt
purpose. The MBDONE interrupt is guaranteed to correspond to a
PDONE/BDONE interrupt when the threshold is set to 1, but offers
interrupt coalescing when the value is > 1.

Since the HW is configured to generate an interrupt when the ring
becomes emtpy, we have to deny any timeout/timer settings coming from
user-space to indicate we can only generate an interrupt very <N>
packets.

While we are at it, fix the DMA_INTR_THRESHOLD_MASK value which was off
by one bit (0xff vs. 0x1ff).

      bnx2x: use ktime_get_seconds() for timestamp · a19a19de
      由 Arnd Bergmann 提交于 
      commit c48f350f "bnx2x: Add MFW dump support" added the
bnx2x_update_mfw_dump() function that reads the current time and stores
it in a 32-bit field that gets passed into a buffer in a fixed format.

This is potentially broken when the epoch overflows in 2038, and
otherwise overflows in 2106. As we're trying to avoid uses of
struct timeval for this reason, I noticed the addition of this
function, and tried to rewrite it in a way that is more explicit
about the overflow and that will keep working once we deprecate
struct timeval.

I assume that it is not possible to change the ABI any more, otherwise
we should try to use a 64-bit field for the seconds right away.

      bnx2: Fix bandwidth allocation for some MF modes · da3cc2da
      由 Yuval Mintz 提交于 
      Management firmware tells driver in case bandwidth configuration for
a specific function exists, but [regretably] the same field has different
meanings depending on the multi-function mode - it can either be
a percentile value or an actual speed.

For newer multi-function modes current logic is incorrect -
driver understands values as actual speeds instead of percentages,
causing the resulting chip configuration to be incorrect.

      net: bcmgenet: Register link_update callback for all MoCA PHYs · 6ac9de5f
      由 Florian Fainelli 提交于 
      Commit 8d88c6eb ("net: bcmgenet: enable MoCA link state change
detection") added a fixed PHY link_update callback for MoCA PHYs when
registered using platform_data exclusively, this change is also
applicable to systems using Device Tree as their primary configuration
interface.

In order for this to work, move the link_update assignment into
bcmgenet_moca_phy_setup() where we know for sure that we are running on
a MoCA GENET instance, and do not override phydev->link since this is:

- properly taken care of by the PHY library by getting the link UP/DOWN
  interrupts
- this now runs everytime we call bcmgenet_open(), so we need to
  preserve whatever we detected before we went administratively DOWN and
  then UP
- we need to make sure that MoCA PHYs start with a link DOWN during
  probe in order to force a link transition to occur

To avoid a forward declaration, move bcmgenet_fixed_phy_link_update()
above its caller.

      net: bcmgenet: Remove checks on clock handles · 7d5d3075
      由 Florian Fainelli 提交于 
      Instead of multiplying the number of checks for IS_ERR(priv->clk),
simply NULLify the 'struct clk' pointer which is something the Linux
common clock framework perfectly deals with and does early return for
each and every single clk_* API functions.

Having every single function check for !IS_ERR(priv->clk) is both
redundant and error prone, as it turns out, we were doing it for the
main GENET clock: priv->clk, but not for the Wake-on-LAN or EEE clock,
so let's just be consistent here.
