Log: MFC r341784 sfxge(4): prepare the number of Tx queues on event queue 0 to become variable The number of Tx queues on event queue 0 can depend on the NIC family type, and this property will be leveraged by future patches. This patch prepares the code for this change. Submitted by: Ivan Malov <Ivan.Malov at oktetlabs.ru> Sponsored by: Solarflare Communications, Inc.
