Would you mind resending this change in a week or two? # Form letter - net-next is closed We have already sent the networking pull request for 5.12 and therefore net-next is closed for new drivers, features, code refactoring and optimizations. We are currently accepting bug fixes only. Please repost when net-next reopens after 5.12-rc1 is cut. Look out for the announcement on the mailing list or check: http://vger.kernel.org/~davem/net-next.html RFC patches sent for review only are obviously welcome at any time.

Changing to napi_gro_receive() improves efficiency significantly. Tested on Intel Core2-based motherboards and iperf3. Signed-off-by: Sieng Piaw Liew <liew.s.piaw@gmail.com> --- drivers/net/ethernet/atheros/atl1c/atl1c_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
