- 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.

The transmit packet descriptor consists of four 32-bit words, with word 3
upper bits overloaded depending upon the condition of its bits 3 and 4.
The driver currently duplicates all word 2 and some word 3 register bit
definitions unnecessarily and also uses a set of nested structures in its
definition of the TPD without good cause. This patch adds a lengthy
comment describing the TPD, eliminates duplicate TPD bit definitions,
and simplifies the TPD structure itself. It also expands the TSO check
to correctly handle custom checksum versus TSO processing using the revised
TPD definitions. Finally, shorten some variable names in the transmit
processing path to reduce line lengths, rename some variables to better
describe their purpose (e.g., nseg versus m), and add a comment or two
to better describe what the code is doing.

The L1 tx packet descriptor expects TCP Header Length to be expressed as a
number of 32-bit dwords.  The atl1 driver uses tcp_hdrlen() to populate the
field, but tcp_hdrlen() returns the header length in bytes, not in dwords.
Add a shift to convert tcp_hdrlen() to dwords when we write it to the tpd.

Also, some of our bit assignments are made to the wrong tpd words.  Change
those to the correct words.

Finally, since all this fixes TSO, enable TSO by default.

The future atl2 driver and the existing atl1 driver can share certain
functions and definitions.  Move these shareable functions and definitions
out of atl1-specific files and into atlx.c and atlx.h.  Some transitory
hackery will be present until atl2 is merged.

Reduce the number of source files by moving ethtool, hw, and param
functions from separate files into atl1_main.c, then rename it to just
atl1.c.

Move all atl1-specific definitions from atl1_hw.h to atl1.h.

Finally, clean up to make checkpatch.pl happy.

Fix locking issues in the pppol2tp driver which can cause a kernel
crash on SMP boxes. There were two problems:-

1. The driver was violating read_lock() and write_lock() scheduling
   rules because it wasn't using softirq-safe locks in softirq
   contexts. So we now consistently use the _bh variants of the lock
   functions.

2. The driver was calling sk_dst_get() in pppol2tp_xmit() which was
   taking sk_dst_lock in softirq context. We now call __sk_dst_get().
