We sometimes run into situations where a soft/hard reset of the adapter
takes a long time or fails to complete. Having additional messages that
include important adapter state info will hopefully help understand what
is happening, reduce the guess work and minimize requests to reproduce
problems with debug patches.

Turned out that mlxsw_sp_ipip_fib_entry_op_gre4() does not need to
figure out the IP address and virtual router id. Those are exactly
the same as in the fib_entry it is called for. So just use that and
reduce mlxsw_sp_ipip_fib_entry_op_gre4() function to only call
mlxsw_sp_ipip_fib_entry_op_gre4_rtdp() make the ipip decap op
code similar to nve.

The attachment of auxiliary drivers to the devices is possible in

so that device (module) will be able to connect to it.

After adding support for QinQ, a.k.a 802.1ad protocol, there are a few
scenarios that should be vetoed.

The vetoes are motivated by various ASIC limitations.
For example, a port that is member in a 802.1ad bridge cannot have 802.1q
uppers as the port needs to be configured to treat 802.1q packets as
untagged packets.

802.1ad, also known as QinQ is an extension to the 802.1q standard, which
is concerned with passing possibly 802.1q-tagged packets through another
VLAN-like tunnel. The format of 802.1ad tag is the same as 802.1q, except
it uses the EtherType of 0x88a8, unlike 802.1q's 0x8100.

Add support for 802.1ad protocol. Most of the configuration is the same
as 802.1q. The difference is that before a port joins an 802.1ad bridge it
needs to be configured to recognize 802.1ad packets as tagged and other
packets (e.g., 802.1q) as untagged.

VXLAN is not currently supported with 802.1ad bridge, so return an error

By default, the device considers both 802.1ad and 802.1q packets as tagged,
but this is not supported by the driver. It only supports VLAN and bridge
devices that use 802.1q protocol.

Instead, configure the device to only treat 802.1q packets as tagged
packets.
