Some lines of code can be merged into an equivalent 'skb_add_rx_frag()' call which is less verbose. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- UNTESTED. Compile tested only The 'skb->truesize' computation is likely to be slightly slower (n additions hidden in 'skb_add_rx_frag' instead of 1 multiplication), but I don't think that it is an issue here. --- drivers/net/ethernet/sfc/rx.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-)
