MFC r339366
Add support for Error Recovery

Submitted by:Vaishali.Kulkarni@cavium.com

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

MFC r307578
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.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

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.

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

It is not network-specific code and would
