qla3xxx: Kernic Panic on pSeries under stress conditions
To reproduce this panic consistently, we run an intensive network
application like 'netperf'. After waiting for a couple of seconds,
you will see a stack trace and a kernel panic where we are calling
pci_unmap_single() in ql_poll().
Changes:
1) Check the flags on the Response MAC IO Control block to check for
errors
2) Ensure that if we are on the 4022 we only use one segment
3) Before, we were reading the memory mapped producer index register
everytime we iterated in the loop when clearing the queue. We should
only be iterating to a known point, not as the producer index
is being updated.

To reproduce this panic consistently, we run an intensive network

We enable interrupts even if we were not running.

This patch adds improved version of enable_fiber for both the 5421 and
the 5461 phy. It is now possible to specify with these wether you want
autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.
Depending on this flag it sets phy->autoneg accordingly for the fiber mode.
More importantly it implements proper read_link and poll_link functions
for both phys which can handle both copper and fiber mode by determining
the medium first and then branching to the required functions. For fiber
they all work fine, for copper they are not tested but return the result
of the genmii_* function anyway which is supposed to work.
The patch moves the genmii_* functions around to avoid foreward declarations.

[SCTP]: Fix connection hang/slowdown with PR-SCTP
The problem that this patch corrects happens when all of the following
conditions are satisfisfied:
1. PR-SCTP is used and the timeout on the chunks is set below RTO.Max.
2. One of the paths on a multihomed associations is brought down.
In this scenario, data will expire within the rto of the initial
transmission and will never be retransmitted. However this data still
fills the send buffer and is counted against the association as outstanding
data. This causes any new data not to be sent and retransmission to not
happen.
The fix is to discount the abandoned data from the outstanding count and
peers rwnd estimation. This allows new data to be sent and a retransmission
timer restarted. Even though this new data will most likely expire within
the rto, the timer still counts as a strike against the transport and forces
the FORWARD-TSN chunk to be retransmitted as well.
