      at91_ether: request/free GPIO for PHY interrupt · 71527ef4
      David Brownell authored 
      When the at91_ether driver is using a GPIO for its PHY interrupt,
be sure to request (and later, if needed, free) that GPIO.

      atl1: fix vlan tag regression · dc5596d9
      Jay Cliburn authored 
      Commit 401c0aab introduced a regression
in the atl1 driver by storing the VLAN tag in the wrong TX descriptor
field.

This patch causes the VLAN tag to be stored in its proper location.

      bonding: fix panic when taking bond interface down before removing module · ce39a800
      Andy Gospodarek authored 
      A panic was discovered with bonding when using mode 5 or 6 and trying to
remove the slaves from the bond after the interface was taken down.
When calling 'ifconfig bond0 down' the following happens:

    bond_close()
        bond_alb_deinitialize()
            tlb_deinitialize()
		kfree(bond_info->tx_hashtbl)
                bond_info->tx_hashtbl = NULL

Unfortunately if there are still slaves in the bond, when removing the
module the following happens:

    bonding_exit()
        bond_free_all()
            bond_release_all()
                bond_alb_deinit_slave()
                    tlb_clear_slave()
                        tx_hash_table = BOND_ALB_INFO(bond).tx_hashtbl
			u32 next_index = tx_hash_table[index].next

As you might guess we panic when trying to access a few entries into the
table that no longer exists.

I experimented with several options (like moving the calls to
tlb_deinitialize somewhere else), but it really makes the most sense to
be part of the bond_close routine.  It also didn't seem logical move
tlb_clear_slave around too much, so the simplest option seems to add a
check in tlb_clear_slave to make sure we haven't already wiped the
tx_hashtbl away before searching for all the non-existent hash-table
entries that used to point to the slave as the output interface.

      bonding: Clean up resource leaks · a434e43f
      Jay Vosburgh authored 
      This patch reworks the resource free logic performed at the time
a bonding device is released.  This (a) closes two resource leaks, one
for workqueues and one for multicast lists, and (b) improves commonality
of code between the "destroy one" and "destroy all" paths by performing
final free activity via destructor instead of explicitly (and differently)
in each path.

"Sean E. Millichamp" <sean@bruenor.org> reported the workqueue
leak, and included a different patch.

I left out the increment of the link failure counter.  This
patch corrects that omission.
