skb->fwd_mark and dev->fwd_mark are 32-bit and should be unique for device
and maybe even unique for a sub-set of ports within device, so add
switchdev helper function to generate unique marks based on driver-supplied
key. Typically, the driver would use device switch ID for key, and maybe
additional fields in key for grouped ports such as bridge ifindex. The key
can be of arbitrary length.
The generator uses a global hash table to store fwd_marks hashed by key.
