There's a number of consumer mainboards where the BIOS leaves the PHY
in a state that it's reporting an invalid PHY ID. To detect such cases
add the PHY ID to the error message if no dedicated PHY driver is found.

Currently there are two callbacks registered: one for matchall,
one for flower. This causes the user to see "in_hw_count 2" in TC filter
dump. Because of this and also as a preparation for future matchall

shared block into matchall.c. Leave only one cb for mlxsw driver

Currently, only the psample_group is accessed using RCU on RX path.
However, it is possible (unlikely) that other sample values get change
during RX processing. Fix this by having the port->sample struct
accessed as RCU pointer, containing all sample values including
psample_group pointer. That avoids extra alloc per-port, copying the
values and the race condition described above.

Two bits in RxConfig are controlled by the following dev->feature's:
- NETIF_F_RXALL
- NETIF_F_HW_VLAN_CTAG_RX (since RTL8125)
We have to take care that RxConfig gets fully configured in
rtl_hw_start() after e.g. resume from hibernation. Therefore:
- Factor out setting the feature-controlled RxConfig bits to a new
function rtl_set_rx_config_features() that is called from
rtl8169_set_features() and rtl_hw_start().
- Don't deal with RX_VLAN_8125 in rtl_init_rxcfg(), it will be set
by rtl_set_rx_config_features().
- Don't handle NETIF_F_RXALL in rtl_set_rx_mode().

Currently, the PF driver removes all (including its VFs') MAC/VLAN
flow director table entries when resetting, and restores them after
reset completed.
In fact, the hardware will clear all table entries only in IMP
reset and global reset. So driver only needs to restore the table
entries in these cases, and needs do nothing when PF reset, FLR
or other function level reset.
This patch optimizes it by removing unnecessary table entries clear
and restoring handling in the reset flow, and doing the restoring
after reset completed.

vport->share_umv_size. And there is already a mutex vport_lock
being defined in the driver, which is designed to protect the
resource of vport. So we can use vport_lock instead of umv_lock.
Furthermore, there is a time window for protect share_umv_size
between checking UMV space and doing MAC configuration in the
lin function hclge_add_uc_addr_common(). It should be extended.

Currently, the HNS3 driver sync and unsync MAC address in function
hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly
in the path of dev_set_rx_mode(). If failed, it won't retry until
next calling of hns3_set_rx_mode(). On the other hand, if request
add and remove a same address many times at a short interval, each
request must be done one by one, can't be merged. For VF, it sends
mailbox messages to PF to request adding or deleting MAC address in
the path of function hns3_set_rx_mode(), no matter the address is
configured success.
This patch refines it by recording the MAC address in function
hns3_set_rx_mode(), and updating MAC address in the service task.
If failed, it will retry by the next calling of periodical service
task. It also uses some state to mark the state of each MAC address
in the MAC list, which can help merge configure request for a same
address. With these changes, when global reset or IMP reset occurs,
we can restore the MAC table with the MAC list.
