- Resubmit #2
- Transmit fifo selection based on TCP/UDP ports.
- Added tx_steering_type loadable parameter for transmit fifo selection.
0x0 NO_STEERING: Default FIFO is selected.
0x1 TX_PRIORITY_STEERING: FIFO is selected based on skb->priority.
0x2 TX_DEFAULT_STEERING: FIFO is selected based on L4 Ports.

- Resubmit #3
Multiqueue netwrok device support implementation.
- Added a loadable parameter "multiq" to enable/disable multiqueue support,
by default it is disabled.
- skb->queue_mapping is not used for queue/fifo selection. FIFO selection is
based on skb->priority.
- Added per FIFO flags FIFO_QUEUE_START and FIFO_QUEUE_STOP. Check this flag
for starting and stopping netif queue and update the flags accordingly.
- In tx_intr_handler added a check to ensure that we have free TXDs before wak-
ing up the queue.
- Added helper functions for queue manipulation(start/stop/wakeup) to invoke
appropriate netif_ functions.
- Calling netif_start/stop for link up/down case respectively.
- As per Andi kleen's review comments, using skb->priority field for FIFO
selection.

Resubmitting patch from Al Viro <viro@zeniv.linux.org.uk>, with subject -
[PATCH] s2io LRO bugs.
a) initiate_new_session() sets ->tcp_ack to ntohl(...); everything
else stores and expects to find there the net-endian value.
b) check for monotonic timestamps in verify_l3_l4_lro_capable()
compares the value sitting in TCP option (right there in the skb->data,
net-endian 32bit) with the value picked from earlier packet.
Doing that without ntohl() is an interesting idea and it might even
work occasionally; unfortunately, it's quite broken.

Multiple transmit fifo initialization -
- Assigned equal scheduling priority for all configured FIFO's.
- Modularized transmit traffic interrupt initialization since it is executed in
s2io_card_up and s2io_link. Enable continuous tx interrupt when link is UP
and vice verse.
- Enable transmit interrupts for all configured transmit fifos.
- Fixed typo errors.

Fixes to enable multiple transmit fifos (upto a maximum of eight).
- Moved single tx_lock from struct s2io_nic to struct fifo_info.
- Moved single ufo_in_band_v structure from struct s2io_nic to struct
fifo_info.
- Assign the respective interrupt number for the transmitting fifo in the
transmit descriptor (TXD).
- Added boundary checks for number of FIFOs enabled and FIFO length.

Drivers do this to try to break out of the ->poll()'ing loop
when the device is being brought administratively down.
Now that we have a napi_disable() "pending" state we are going
to solve that problem generically.

Fix the case when the card initialization fails on a mtu change and then
close is called (due to ifdown), which frees non existent rx buffers.
- Returning appropriate error codes in init_nic function.
- In s2io_close function s2io_card_down is called only when device is up.
- In s2io_change_mtu function return value of s2io_card_up function
is checked and returned if it failed.
