tanx.
out of curiosity, can some one pls. explain this?
In if_em.c, function em_start_locked, there is:
if (txr->tx_avail <= EM_TX_CLEANUP_THRESHOLD)
em_txeof(txr);
inside while loop. While is if_igb.c, function igb_start_locked,
a similar code it is out of while loop:
if (txr->tx_avail <= IGB_TX_CLEANUP_THRESHOLD)
igb_txeof(txr);
is this intentional or mistake?
