This may have something to do with the bug in my previous pr, but it is not solved by removing the 'EARLY_RX' define --- which makes me uncomfortable in general. When skip is enabled, a tcpdump on another machine on the same ethernet will show 'truncated packet' for each ping packet that the host is trying to return. >How-To-Repeat: Configur and install /usr/ports/security/skip on two machines, one of which has a tx0. Ping in either direction while a third host watches the ethernet. You will see 'truncated' packets. >Fix: I have had to replace tx0 cards with other cards to use skip. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
