Chien Tung 7b14ab0b43 RDMA/nes: Fix tmp_addr compilation warning
In find_node(), tmp_addr causes an "unused variable" warning when
INFINIBAND_NES_DEBUG is not defined.  It's only used in a nes_debug()
and the print does not make sense.  So take out the whole thing.

Harvey Harrison 03080e5cbe RDMA/nes: Fix for NIPQUAD removal
Commit 63779436 ("drivers: replace NIPQUAD()") accidentally replaced
some HIPQUAD()s, causing IP addresses to be printed in reverse order.
Add temporary local vars until the byteswapping can be pushed further
up the stack.

Coly Li 73ac36ea14 fix similar typos to successfull
When I review ocfs2 code, find there are 2 typos to "successfull".  After
doing grep "successfull " in kernel tree, 22 typos found totally -- great
minds always think alike :)

This patch fixes all the similar typos. Thanks for Randy's ack and comments.

Faisal Latif e189062a8c RDMA/nes: Remove tx_free_list
There is no lock protecting tx_free_list thus causing a system crash
when skb_dequeue() is called and the list is empty.  Since it did not give
any performance boost under heavy load, remove it to simplify the code.
Replace get_free_pkt() with dev_alloc_skb() to allocate MAX_CM_BUFFER skb
for connection establishment/teardown as well as MPA request/response.

Faisal Latif 183ecfa309 RDMA/nes: Avoid race between MPA request and reset event to rdma_cm
In passive open, after indicating MPA request to rdma_cm, an incoming
RST would fire a reset event to rdma_cm causing it to crash, since the
current state is not connected.  The solution is to wait for
nes_accept() or nes_reject() before firing the reset event.  If
nes_accept() or nes_reject() is already done, then the reset event
will be fired when RST is processed.

Chien Tung bc5698f3ec RDMA/nes: Fix adapter reset after PXE boot
After PXE boot, the iw_nes driver does a full reset to ensure the card
is in a clean state.  However, it doesn't wait for firmware to
complete its work before issuing a port reset to enable the ports,
which leads to problems bringing up the ports.

The solution is to wait for firmware to complete its work before
proceeding with port reset.
