Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this issue, but failed to set the correct IP checksum when receiving GSO packets via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed to calculate IP checksum were erroneously set in the incorrect buffer descriptor. This patch re-enables GSO in said scenario for 57710/57711 chips. Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: Eilon Greenstein Signed-off-by: David S.
