dwc: improve IPv4 transmit checksum offloading
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.
