net: dsa: Allow switch drivers to indicate number of TX queues
Let switch drivers indicate how many TX queues they support. Some switches, such as Broadcom Starfighter 2 are designed with 8 egress queues. Future changes will allow us to leverage the queue mapping and direct the transmission towards a particular queue. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
