EM anchors list initialization for only master port was not enough to
keep npiv working as described here:-
https://lists.open-fcoe.org/pipermail/devel/2011-January/011063.html
So this patch moves fc_exch_mgr_list_clone to update npiv ports
EMs once EM anchors list initialized.
Also some cleanup, no need to set lport = NULL as that always
get initialized later.

itself is timed out"
When abort for an exchange timed out it didn't release the reference to
the exchange resulting in a memory leak.
After discussion with the author of the patch (CC) that introduced this
bug it was suggested to revert that patch.
This reverts commit ea3e2e72eeb3e8a9440a5da965914f9b12088626.

When an fcoe interface is being destroyed; in the process the
fcoe driver will try to release all the resources it had allocated
for that interface including rports. But, it seems that it does not
release the reference held for the name server rport in that process
resulting into a memory leak. This patch fixes that memory leak.

Instead of blocking the entire host when the port's

If the port takes a while to transition we could exhaust
the retries when using DID_TRANSPORT_DISRUPTED. For this
case we do not want to use any of the cmd's
retries, because if the command was running then when
it got failed the retry counter was already incremented.
And if this is the first time we are seeing the command,
(it got queued because it slipped through during the race)
then it should not have its retries incremented. The
fc class will decide the correct handling later.

The 'k' in the version in the past will be removed.

The fc_block_scsi_eh() might return with status FAST_IO_FAIL
indicating I/O has been terminated due to fast_io_fail timeout.
In this case the rport is still blocked, so any error recovery
will be failing on this port. Hence we need to check if the
return value from fc_block_scsi_eh() is something other than 0,
in which case it should just return with that status.

Based on reading of the FCP2/4 specification, the driver cannot

By not clearing the 'login needed' nor 'login outstanding' states
for an fcport after a big-hammer (adapter reset), the driver may
not properly perform a PLOGI/PRLI sequence (and lose visibility
to the rport) during a follow-on SNS scan.

bnx2i has some checks to try and make sure the ep
is not destroyed while the addr/port is getting
read. However, if after this check:
if (!(bnx2i_conn && bnx2i_conn->ep && bnx2i_conn->ep->hba))
goto out;
bnx2i_conn->ep is cleared by ep_disconnect then we will
oops.
This patches fixes the problem by having the driver
use the get_ep_param callback instead of get_conn_param.

For drivers using the ep callbacks the addr and port
are attached to the endpoint instead of the conn.
This adds a callout to the iscsi_transport to get
ep values. It also adds locking around the get
param call to make sure that ep_disconnect does
not free the LLD's ep interconnect structs from
under us (the ep has a refcount so it will not
go away but the LLD may have structs from other
subsystems that are not allocated in the ep so
we need to protect them from getting freed).

This has iscsi_tcp use the iscsi_conn_get_addr_param
libiscsi function. It also drops the use of the libiscsi
session portal buffers, so they can be removed in
the next patches. Instead of copying the values
at bind time we get them during get() time. If we are
not connected userspace will now get -ENOTCONN,
so it knows that connection is disconnected instead
of a possible stale value.
