niu: Naming interrupt vectors.
A patch to put names on the niu interrupt vectors according the syntax below. This is needed to assign correct affinity. > So on a multiqueue card with 2 RX queues and 2 TX queues we'd > have names like: > > eth0-rx-0 > eth0-rx-1 > eth0-tx-0 > eth0-tx-1 Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Tested-by: Jesper Dangaard Brouer <jdb@comx.dk> Signed-off-by: David S.
