bonding:reset backup and inactive flag of slave

Eduard Sinelnikov (eduard.sinelnikov@gmail.com) found that if we change
bonding mode from active backup to round robin, some slaves are still keeping
"backup", and won't transmit packets.

As Jay Vosburgh(fubar@us.ibm.com) pointed out that we can work around that by
removing the bond_is_active_slave() check, because the "backup" flag is only
meaningful for active backup mode.

But if we just simply ignore the bond_is_active_slave() check,
the transmission will work fine, but we can't maintain the correct value of
"backup" flag for each slaves, though it is meaningless for other mode than
active backup.

I'd like to reset "backup" and "inactive" flag in bond_open,
thus we can keep the correct value of them.

As for bond_is_active_slave(), I'd like to prepare another patch to handle it.

V2:
Use C style comment.
Move read_lock(&bond->curr_slave_lock).
Replace restore with reset, for active backup mode, it means "restore",
but for other modes, it means "reset".

If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on

when plx_pci_del_card is later called, it may get freed again.  So that
entry is reset to NULL after the free.

Finally, if there is a problem with one channel, there will be a hole in the
array.  card->channels counts the number of channels that have succeeded,
and does not keep track of the index of the largest element in the array

e1000e: workaround invalid Tx/Rx tail descriptor register write

When the Manageability Engine (ME) is enabled on 82579, it periodically
accesses some MAC CSR registers.  There is an arbiter in hardware which
prevents simultaneous access of these registers by the host software, i.e.
the driver.  There is a hardware bug in the aribter that signals a host
access of the registers later than it actually happens.  A write of the
Transmit or Receive Descriptor Tail register could result in an incorrect
value if the driver and ME perform simultaneous accesses which could result
in an access to an invalid memory address.  This would return an
Unsupported Request which could hang the hardware.  Workaround the issue by
checking the FWSM register bit24 which is set by ME before it accesses the
MAC CSR registers.

an interrupt request in-band message, it would trigger a false interrupt.

By reducing the number of preamble octets stripped from the beginning of
the frame when passing it from the PHY to the MAC, the MAC will interpret
the frame properly.
