sfc: Add support for TX MAC filters
On Siena each TX queue can be configured to send only packets for which there is a TX MAC filter that matches the source MAC address, queue ID, and optionally VID. This will be used to implement the 'spoofchk' feature for SR-IOV virtual functions. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
