bge: disable TXCSUM if UDP transmit checksum offloading is disabled

2026-01-16T12:36:53+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.

bus_generic_detach: Delete children after detaching them

2025-01-02T18:21:30+00:00

This provides better semantics as a standalone DEVMETHOD for
device_attach as bus drivers should remove child devices they created
as part of detach cleanup.  The implementation calls
bus_detach_children() first to permit child devices an opportunity to
veto the detach operation.  If that succeeds, device_delete_children()
is used to delete the child devices.

This requires fixing various drivers that were deleting devices
explicitly (via a device_t pointer cached in the softc) after calling
bus_generic_detach to stop doing that and just rely on
bus_generic_detach to remove child devices.

Change 4787572d0580 made if_alloc_domain() never fail, then also do the
wrappers if_alloc(), if_alloc_dev(), and if_gethandle().

No functional change intended.

IfAPI: Retire if_etherbpfmtap() and if_bpfmtap()

2023-08-25T16:50:14+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.
