This > patch adds a conditional update of last_rx to the bonding special logic > in skb_bond_should_drop, causing last_rx to only be updated when the ARP > monitor is running. > > This frees network device drivers from the necessity of updating > last_rx, which can have cache line thrash issues. > > Signed-off-by: Jay Vosburgh <fubar@...ibm.com> Applied, thanks a lot Jay. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
