[E1000-devel] e1000 rx_ring[0] protection

[Lal <lea...@gm...>]

In e1000_clean function in drivers/net/e1000_main.c file, tx_ring[0]
is protected by spin lock to prevent from being cleaned by multiple
cpus simultaneously, but rx_ring[0] is not.

Why rx_ring[0] is not protected from multiple cpus ?

Thanks
