      vxge: update MAINTAINERS · e3806882
      Jon Mason authored
      Exar has exited the 10G Ethernet NIC market, orphaning both the s2io and
      vxge drivers.  With the promise of free hardware, I'll take over
      maintainership.

      r6040: fix multicast operations · c60c9c71
      Shawn Lin authored
      The original code does not work well when the number of mulitcast
      address to handle is greater than MCAST_MAX. It only enable promiscous
      mode instead of multicast hash table mode, so the hash table function
      will not be activated and all multicast frames will be recieved in this
      condition.
      
      This patch fixes the following issues with the r6040 NIC operating in
      multicast:
      
      1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC
      hash table registers to make it process multicast traffic.
      
      2) When the number of multicast address to handle is smaller than
      MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}.
      
      3) The hashing of the address was not correct, due to an invalid
      substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an
      incorrect crc algorithm (ether_crc_le) instead of (ether_crc).
      
      4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast
      hash table function.

      bonding 802.3ad: Rename rx_machine_lock to state_machine_lock · 9ac3524a
      Nils Carlson authored
      Rename the rx_machine_lock to state_machine_lock as this makes more
      sense in light of it now protecting all the state machines against
      concurrency.

      bonding 802.3ad: Fix the state machine locking v2 · 16d79d7d
      Nils Carlson authored
      Changes since v1:
      * Clarify an unclear comment
      * Move a (possible) name change to a separate patch
      
      The ad_rx_machine, ad_periodic_machine and ad_port_selection_logic
      functions all inspect and alter common fields within the port structure.
      Previous to this patch, only the ad_rx_machines were mutexed, and the
      periodic and port_selection could run unmutexed against an ad_rx_machine
      trigged by an arriving LACPDU.
      
      This patch remedies the situation by protecting all the state machines
      from concurrency. This is accomplished by locking around all the state
      machines for a given port, which are executed at regular intervals; and
      the ad_rx_machine when handling an incoming LACPDU.
