1. state checks in bxe_tx_mq_start_locked() and bxe_tx_mq_start() to
sync threads during interface down or detach.
2. add sysctl to set pause frame parameters
3. increase max segs for TSO packets to BXE_TSO_MAX_SEGMENTS (32)
4. add debug messages for PHY
5. HW LRO support restricted to FreeBSD versions 8.x and above.

1. Use taskqueue_create() instead of taskqueue_create_fast() for both
fastpath and slowpath taskqueues.
2. Service all transmits in taskqueue threads.
3. additional stats counters for keeping track of
- bd availability
- tx buf ring not emptied in the fp task queue.
These are drained via timeout taskqueue.
- tx attempts during link down.

1. modify fwdump (a.k.a grcdump) so that grcdump memory is allocated
and freed on as needed basis.
2. grcdump can be taken at failure points by invoking bxe_grc_dump()
when trigger_grcdump sysctl flag is set. When grcdump is taken
grcdump_done sysctl flag is set.
3. grcdump_done can be monitored by the user to retrieve the grcdump

Modifications to achieve a common source base from FreeBSD7.x thru 10.x

MFC r296071
Upgrade the firmware carried in driver and loaded during hardware
initialization (a.k.a STORM firmware) to version 7.13.1 (latest version)

MFC r295830
Remove dead code. Code Cleanup. Improve clarity in debug messages

MFC r295823

Modified the use of bxe_grc_dump() function so that it can be invoked directly
at any potential error path, where a fwdump is needed.
The fwdump (a.k.a grcdump) is stored in a driver buffer.
The sysctl grcdump_done indicates if a fwdump was taken and waiting to be retrieved.
The sysctl trigger_grcdump can be used to manually trigger a fwdump.

- Avoid lock contention in the if_transmit callback by using trylock and
enqueueing the frames when it fails. This way there is some latency
removed from the transmitting path.
- If IFF_DRV_OACTIVE is set (and also if IFF_DRV_RUNNING is not) just
enqueue the desired frames and return successful transmit. This way we
avoid to return errors on transmit side and resulting in
possible out-of-order frames. Please note that IFF_DRV_OACTIVE is set
everytime we get the threshold ring hit, so this can be happening quite
often.

PHY LOCK acquires the hardware lock via bxe_acquire_phy_lock() and releases it via bxe_release_phy_lock(). It was simply acquiring a mutex earlier which can cause the PHY to use bogus values. Fixes intermittent link failures.

bxe_ioctl() completes all functions within its context as opposed to a taskqueue earlier.

bxe_handle_rx_mode_tq() no longer required. bxe_set_rx_mode() handles the functionality within its context

Initiate error recovery stats fail to update after 3 retries.
Change bxe_panic() ECORE_DBG_BREAK_IF() ECORE_BUG() ECORE_BUG_ON() to
panic only if ECORE_STOP_ON_ERROR is defined.
