If anyone has any objections, please let me know. ------------------ From: Manish Chopra [ Upstream commit 58f101bf87e32753342a6924772c6ebb0fbde24a ] Today, driver drops received packets which are indicated as invalid checksum by the device. Instead of dropping such packets, pass them to the stack with CHECKSUM_NONE indication in skb. Signed-off-by: Ariel Elior Signed-off-by: Manish Chopra Signed-off-by: David S.
