842158d7b7 [SCSI] bnx2i: Modified the bnx2i stop path to compensate for in progress ops
The stop path has been augmented to wait a max of 10s for all in
progress offload and destroy activities to complete before proceeding
to terminate all active connections (via iscsid or forcefully).

Note that any new offload and destroy requests are now blocked and
return to the caller immediately.

250ae982e2 [SCSI] bnx2i: Added chip cleanup for the remove module path
In the case when an ep_connect request is interrupted due to route
request stall, if the iSCSI daemon is terminated by the user, the chip
will be left in a state which will not get cleaned up upon module
removal.  Upon module reload, when the same context id is used for a
new connection, chip panic would occur.

This patch adds chip cleanup in the module removal path.

55e15c975c [SCSI] bnx2i: Optimized the bnx2i_stop connection clean up procedure
For cases where the iSCSI disconnection procedure times out due to
the iSCSI daemon being slow or unresponsive, the bnx2i_stop routine
will now perform hardware cleanup via bnx2i_hw_ep_disconnect on all
active endpoints so that subsequent operations will perform properly.
Also moved the mutex locks inside ep_connect and ep_disconnect so
that proper exclusivity can resolve simultaneous calls to the
ep_disconnect routine.

v2: Removed the unnecessary read lock in the bnx2i_stop

490475a993 [SCSI] bnx2i: Bug fixes related to MTU change issue when there are active iscsi sessions
bnx2i driver has to wait and cleanup all iscsi endpoints before
returning from bnx2i_stop(). This is to make sure all chip resources
are freed before chip is reset.

As the requirements for 1G and 10G chipsets is different, added
per-device 'hba_shutdown_tmo' parameter to adapter structure

If the connections are not torn down by the daemon within this timeout
period, 'cid's will be leaked in 10G device. 1G devices are more
flexible and do not leak any resources because the whole chip ports
gets reset when MTU is changed or ethtool selftest is run

fixed a minor issue in bnx2i_ep_poll() which unnecessarily forced
error return code when driver timed out waiting for TCP connect
request to complete

ce2d763a2c [SCSI] bnx2i: link bnx2i hba and cnic device before registering the device
When bnx2/cnic/bnx2i drivers are loaded in certain order, bnx2i will
will not initialize the device correctly because 'hba->cnic' will be
NULL when bnx2i_start() is called from register_device() context.
Under this condition 'ifdown' and 'ifup' of associated network
interface is required to bring iscsi adapter state to ready state so
that it will accept iscsi connection setup within the chip

Initializing 'hba->cnic' before calling register_device() will fix
this issue

f8c9abe797 [SCSI] bnx2i: Adjust sq_size module parametr to power of 2 only if a non-zero value is specified
This issue was discovered during 10G iscsi testing

Default value of 'sq_size' module parameter is '0' which means driver
should use predefined SQ queue size when setting up iscsi connection.

roundup_pow_of_two(0) results in '1' and forces driver to setup
connections with send queue size of '1' and results in lower
performance as well

fac3cc458f [SCSI] bnx2i: register given device with cnic if shost != NULL in ep_connect()
When using iface, bnx2i was unable to offload further connections after all
active sessions are logged out. bnx2i will unregister the device from cnic
when the last connection is torn down. Next call to ep_connect() will fail
because the device is not registered. This issue is not seen if shost == NULL
is passed to ep_connect() call because in that case bnx2i will registers all
known devices with cnic before doing a route look-up.  When shost != NULL,
bnx2i knows the device on which to offload the connection and has to register
this device before attempting to offload the connection
