[net-next v3 00/15] ethernet: Convert from tasklet to BH workqueue

The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.

This patch converts a few drivers in drivers/ethernet/* from tasklet
to BH workqueue. The next set will be sent out after the next -rc is
out.

This series is based on
1722389b0d86 (Merge tag 'net-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net)

[v3]:
  - Include Reviewed-by signature
  - hinic: can show work_pending() as a partial replacement for the tasklet state.
  - mvpp2: retain and re-word comment.
  - fix rxempty_bh_work() which will emit 'RX Queue Full!'
     message, so the change should be visibile to the user.
