[PATCHv2,0/2] ipoib bugfix

Message

We run into queue timeout often with call trace as such:
NETDEV WATCHDOG: ib0.beef (): transmit queue 26 timed out
Call Trace:
call_timer_fn+0x27/0x100
__run_timers.part.0+0x1be/0x230
? mlx5_cq_tasklet_cb+0x6d/0x140 [mlx5_core]
run_timer_softirq+0x26/0x50
__do_softirq+0xbc/0x26d
asm_call_irq_on_stack+0xf/0x20
ib0.beef: transmit timeout: latency 10 msecs
ib0.beef: queue stopped 0, tx_head 0, tx_tail 0, global_tx_head 0, global_tx_tail 0

The last two message repeated for days.

After cross check with Mellanox OFED, I noticed some bugfix are missing in
upstream, hence I take the liberty to send them out.

Thx!

v2:
Fix the build error due to napi api change in v6.7
