This patch changes the multi-block allocation code, such that
directory inodes only get a single block reserved in the bitmap.
That way, the bitmaps are more tightly packed together, and there
are fewer spans of free blocks for in-use block reservations.
This means it takes less time to find a free span of blocks in the
bitmap, which speeds things up. This increases the performance of
some workloads by almost 2X. In Nate's mockup.py script (which does
(1) create dir, (2) create dir in dir, (3) create file in that dir)
the test executes in 23 steps rather than 43 steps, a 47%
performance improvement.

for a new firmware feature to force an adapter to use 32 bit MSIs.
However, this firmware is not available for all systems. The hack below
allows devices needing 32 bit MSIs to work on these systems as well.
It is careful to only enable this on Gen2 slots, which should limit
this to configurations where this hack is needed and tested to work.

In function be_get_nic_desc(), it will go through the descriptor array
returned from f/w. By comparing the desc_type field, it determines whether
there is a nic descriptor in the array or not. In the case of no nic
descriptor, this function should return NULL.

The code may return an invalide descriptor, when there is no nic descriptor
in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case,
even there is no nic descriptor, it will still return the lase descriptor
since the i doesn't equal to MAX_RESOURCE_DESC.

This patch fix this issue by returning the descriptor when find it and return
NULL for other cases.

This patch is a fix for a bug triggering newly_acked_sacked < 0
in tcp_ack(.).

The bug is triggered by sacked_out decreasing relative to prior_sacked,
but packets_out remaining the same as pior_packets. This is because the
snapshot of prior_packets is taken after tcp_sacktag_write_queue() while
prior_sacked is captured before tcp_sacktag_write_queue(). The problem
is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment)
adjusts the pcount for packets_out and sacked_out (MSS change or other
reason). As a result, this delta in pcount is reflected in
(prior_sacked - sacked_out) but not in (prior_packets - packets_out).

This patch does the following:
1) initializes prior_packets at the start of tcp_ack() so as to
capture the delta in packets_out created by tcp_fragment.
2) introduces a new "previous_packets_out" variable that snapshots
packets_out right before tcp_clean_rtx_queue, so pkts_acked can be
correctly computed as before.
3) Computes pkts_acked using previous_packets_out, and computes
newly_acked_sacked using prior_packets.
