Previously, hns3 driver just directly send specific setting bit
and mask bits of MAC VLAN switch parameter to the firmware, it
can not be compatible with the old firmware, because the old one
ignores mask bits and covers all bits with new setting bits.
So when running with old firmware, the communication between PF
and VF will fail after resetting or configuring spoof check, since
they will do the MAC VLAN switch parameter configuration.
This patch fixes this problem by reading switch parameter firstly,
then just modifies the corresponding bit and sends it to firmware.

The current loopback mode is to add 0x1F to the SMAC address
as the DMAC address and enable the promiscuous mode.
However, if the VF address is the same as the DMAC address,
the loopback test fails.
Loopback can be enabled in three places: SSU, MAC, and serdes.
By default, SSU loopback is enabled, so if the SMAC and the DMAC
are the same, the packets are looped back in the SSU. If SSU loopback
is disabled, packets can reach MAC even if SMAC is the same as DMAC.
Therefore, this patch disables the SSU loopback before the loopback
test. In this way, the SMAC and DMAC can be the same, and the
promiscuous mode does not need to be enabled. And this is not
valid in version 0x20.
This patch also uses a macro to replace 0x1F.

Currently, the reset interrupt is cleared in the reset task, which
is too late. Since, when the hardware finish the previous reset,
it can begin to do a new global/IMP reset, if this new coming reset
type is same as the previous one, the driver will clear them together,
then driver can not get that there is another reset, but the hardware
still wait for the driver to deal with the second one.
So this patch clears PF's reset interrupt status in the
hclge_irq_handle(), the hardware waits for handshaking from
driver before doing reset, so the driver and hardware deal with reset
one by one.
BTW, when VF doing global/IMP reset, it reads PF's reset interrupt
register to get that whether PF driver's re-initialization is done,
since VF's re-initialization should be done after PF's. So we add
a new command and a register bit to do that. When VF receive reset
interrupt, it sets up this bit, and PF finishes re-initialization
send command to clear this bit, then VF do re-initialization.
