Since that feature is in the upper 32 bits of a 64 bit variable the result was always 0 making it not possible to actually turn off the hardware RX checksum support. Change the unsigned int type to the netdev_features_t type in order to properly capture the current value and perform the proper operation. Signed-off-by: Tom Lendacky Signed-off-by: David S.
