dwc: add receive checksum offload for IPv6

2026-01-21T15:15:50+00:00

This patch adds support for receive checksum offload for TCP/IPv6
and UDP/IPv6. Since receive checksum offload can't be configured
separately for IPv4 and IPv6, IFCAP_RXCSUM and IFCAP_RXCSUM_IPV6
can't be changed independently.

dwc: improve IPv4 transmit checksum offloading

2026-01-21T14:04:21+00:00

This patch provides two improvements for TCP/IPv4 and UDP/IPv4
transmit checksum offloading:
(1) Use *CIC_SEG instead of *CIC_FULL, since FreeBSD always provides
    a pseudo header checksum.
(2) Don't make transmit IPv4 header checksum offloading a prerequisite
    for TCP/IPv4 or UDP/IPv4 transmit checksum offloading.
This is the root cause of PR 291696, since right now the epair
interface does not support transmit IPv4 header checksum offloading,
but TCP/IPv4 and UDP/IPv4 transmit checksum offloading.

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.

dwc(4): Use bool rather than boolean_t.

This was already using true/false rather than TRUE/FALSE.
