net/macb: Factor out one-time assignment from loop
In 02c958dd3 (net/macb: add TX multiqueue support for gem), the initialization of tx_head and tx_tail in macb_init_rings() was moved inside the loop that iterates over each element in the ring. Since tx_head and tx_tail only need to be assigned once, move them back out of the loop. Signed-off-by: Ben Shelton <ben.shelton@ni.com> Signed-off-by: David S. Miller <davem@davemloft.net>
