The calculation of "wqe_size" is not correct when the tx queue is busy in
hinic_xmit_frame().
When there are no free WQEs, the tx flow will unmap the skb buffer, then
ring the doobell for the pending packets. But the "wqe_size" which used
to calculate the doorbell address is not correct. The wqe size should be
cleared to 0, otherwise, it will cause a doorbell error.
This patch fixes the problem.

This was detected by the self-test thanks to Ard's chunking patch.
I finally got around to testing this out on my ancient Via box. It
turns out that the workaround got the assembly wrong and we end up
doing count + initial cycles of the loop instead of just count.
This obviously causes corruption, either by overwriting the source
that is yet to be processed, or writing over the end of the buffer.
On CPUs that don't require the workaround only ECB is affected.
On Nano CPUs both ECB and CBC are affected.
This patch fixes it by doing the subtraction prior to the assembly.

This is a test of the ISA 3.0 "copy" instruction. That instruction has
an L field, which if set to 1 specifies that "the instruction
identifies the beginning of a move group" (pp 858). That's also
referred to as "copy first" vs "copy".
In ISA 3.0B the copy instruction does not have an L field, and the
corresponding bit in the instruction must be set to 1.
This test is generating a "copy" instruction, not a "copy first", and
so on Power9 (which implements 3.0B), this results in an illegal
instruction.
So just drop the test entirely. We still have copy_first_unaligned to
test the "copy first" behaviour.

The Marvell switches report their interrupts in a level sensitive way.
When using edge sensitive detection a race condition in the interrupt
handler of the swich might result in the OS to miss all future events
which might make the switch non-functional.
The problem is that both mv88e6xxx_g2_irq_thread_fn() and
mv88e6xxx_g1_irq_thread_work() sample the irq cause register
(MV88E6XXX_G2_INT_SRC and MV88E6XXX_G1_STS respectively) once and then
handle the observed sources. If after sampling but before all observed
irq sources are handled a new irq source gets active this is not noticed
by the handler which returns unsuspecting, but the interrupt line stays
active which prevents the edge detector to kick in.
All device trees but imx6qdl-zii-rdu2 get this right (most of them by
not specifying an interrupt parent). So fix imx6qdl-zii-rdu2
accordingly.

There is an issue that link reset can't recover PHY when STP link timeout.
Because current process of enabling PHY for v3 hw will wait last
transmission done. The time of one transmission depends IO size, disk model
and so on. Normally, it should be shorter than 50ms. But the last
transmission could be never done for some abnormal scenarios, such as STP
link timeout.
This patch is to fix the issue. Check PHY status after starting process of
enabling PHY for 50ms. If the PHY is still active, we disable it forcibly
by PHY reset. Of course, we need to clear the PHY reset bit when enable
PHY.
Besides, the function disable_phy_v3_hw() should not be suitable to call in
interrupts for hilink bug for this 50ms delay. Then, we do link reset for
hilink bug directly. The change is that we don't clear the invalid dword
count register. This is better. Because we should not clear such error
count while not saved.
