bge: disable TXCSUM if UDP transmit checksum offloading is disabled

2026-01-21T14:11:56+00:00

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.

IfAPI: Retire if_etherbpfmtap() and if_bpfmtap()

2025-09-03T04:36:30+00:00

Summary:
These came in the original DrvAPI commits in 2014, and are obsoleted by
bpf_mtap_if() and ether_bpf_mtap_if().  The `_if` suffix, rather than
prefix, conveys that it's operating on the bpf of the interface, instead
than the interface itself.
