Michael Tuexen a148f7e54c bge: disable TXCSUM if UDP transmit checksum offloading is disabled ... The bge interface is special with respect to transmit checksumi offloading. In the default settings, an bge interface announces TXCSUM capabilities, but only supports TCP/IPv4 and not UDP/IPv4 due to limitations of some of the NICs. This results in problems when the bge interface becomes a member of a bridge. Since currently only the TXCSUM capabilities are synced when a member is added to a bridge and not the protocol specific capabilities, this can result in a situation where UDP packets are sent out using a bge interface without having a correct checksum. To mitigate this problem, initially don't announce TXCSUM capabilities, when UDP transmit checksum is disabled. It is still possible to enable TXCSUM capabilities via ifconfig.
