There is no reason for the arbitrary restriction that device must be
up to create a vlan. This patch was added to Vyatta kernel to resolve startup
ordering issues where vlan's are created but real device was disabled.
Note: the vlan already correctly inherits the operstate from real device; so
if vlan is created and real device is marked down, the vlan is marked
down.

Some USB devices crash when we send them an inquiry with the EVPD bit
set, regardless of page requested (i.e. including page 0).
We only need the extended inquiry to gain access to VPD pages 0xB0 and
0xB1. These appeared in SBC2 and SBC3 respectively, so we can restrict
sending the extended inquiry to devices reporting SPC3 or higher.

Currently the fc_exch_rrq is called with fc_exch's ex_lock held.
The fc_exch_rrq allocates new exch and that requires taking
ex_lock again after EM lock. This locking order causes warning,
see more details on this warning at :-
http://www.open-fcoe.org/pipermail/devel/2009-July/003251.html
This patch fixes this by dropping the ex_lock before calling
fc_exch_rrq().
The fc_exch_rrq needs to grab ex_lock lock again to schedule
RRQ retry and in the meanwhile fc_exch_reset could occur before
ex_lock is grabbed inside fc_exch_rrq. So to handle this case,
this patch adds additional check to detect fc_exch_reset after
ex_lock acquired and in case the fc_exch_reset occurred then
abandons the RRQ retry and releases the exch.

Recently dm-multipath began calling blk_abort_queue. This causes all the
commands/request running on the path to have the timeout function called.
If a path does go down, and the LLD returns DID_*, dm-multpiath will eventually
get this error and begin to call the cmd timeout handler. qla4xxx currently
does not set a timed out handler and so the default one could return
BLK_EH_NOT_HANDLED and end up firing the scsi eh and stopping IO to all
paths on the host when only one path is affected.
For software and offload iscsi we have a timed out handler already.
This patch adds a driver specific one to qla4xxx because there
are some ddb->state and session->state and command completion races
that are better handled in the LLD.
This also handles the problem where if the session is down,
we do not need the scsi eh to run until the transport code
has tried to reconnect us.
