      [SCSI] fcoe, libfc: fully makes use of per cpu exch pool and then removes em_lock · b2f0091f
      由 Vasu Dev 提交于 
      1. Updates fcoe_rcv() to queue incoming frames to the fcoe per
   cpu thread on which this frame's exch was originated and simply
   use current cpu for request exch not originated by initiator.
   It is redundant to add this code under CONFIG_SMP, so removes
   CONFIG_SMP uses around this code.

2. Updates fc_exch_em_alloc, fc_exch_delete, fc_exch_find to use
   per cpu exch pools, here fc_exch_delete is rename of older
   fc_exch_mgr_delete_ep since ep/exch are now deleted in pools
   of EM and so brief new name is sufficient and better name.

   Updates these functions to map exch id to their index into exch
   pool using fc_cpu_mask, fc_cpu_order and EM min_xid.
   This mapping is as per detailed explanation about this in
   last patch and basically this is just as lower fc_cpu_mask
   bits of exch id as cpu number and upper bit sum of EM min_xid
   and exch index in pool.

   Uses pool next_index to keep track of exch allocation from
   pool along with pool_max_index as upper bound of exches array
   in pool.

3. Adds exch pool ptr to fc_exch to free exch to its pool in
   fc_exch_delete.

4. Updates fc_exch_mgr_reset to reset all exch pools of an EM,
   this required adding fc_exch_pool_reset func to reset exches
   in pool and then have fc_exch_mgr_reset call fc_exch_pool_reset
   for each pool within each EM for a lport.

5. Removes no longer needed exches array, em_lock, next_xid, and
   total_exches from struct fc_exch_mgr, these are not needed after
   use of per cpu exch pool, also removes not used max_read,
   last_read from struct fc_exch_mgr.

6. Updates locking notes for exch pool lock with fc_exch lock and
   uses pool lock in exch allocation, lookup and reset.

      net: convert unicast addr list · ccffad25
      由 Jiri Pirko 提交于 
      This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).

I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.

The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

      fcoe: adds spma mode support · 184dd345
      由 Vasu Dev 提交于 
      If we can find a type NETDEV_HW_ADDR_T_SAN mac address from the
corresponding netdev for a fcoe interface then sets up added the
fc->ctlr.spma flag and stores spma mode address in ctl_src_addr.

In case the spma flag is set then:-

 1. Adds spma mode MAC address in ctl_src_addr as secondary
    MAC address, the FLOGI for FIP and pre-FIP will go out
    using this address.
 2. Cleans up stored spma MAC address in ctl_src_addr in
    fcoe_netdev_cleanup.
 3. Sets up spma bit in fip_flags for FIP solicitations along
    with exiting FPMA bit setting.
 4. Initialize the FLOGI FIP MAC descriptor to stored spma
    MAC address in ctl_src_addr. This is used as proposed
    FCoE MAC address from initiator along with both SPMA
    and FPMA bit set in FIP solicitation, in response the
    switch may grant any FPMA or SPMA mode MAC address to
    initiator.

Removes FIP descriptor type checking against ELS type
ELS_FLOGI in fcoe_ctlr_encaps to update a FIP MAC descriptor,
instead now checks against FIP_DT_FLOGI.

I've tested this with available FPMA-only FCoE switch but
since data_src_addr is updated using same old code for
both FPMA and SPMA modes with FIP or pre-FIP links, so added
SPMA mode will work with SPMA-only switch also provided that
switch grants a valid MAC address.
