Yes, and the point is to make it not use them *ever*, no matter what the MTU is. 9k clusters are Bad News; given the choice I would just as soon rip out all the code for greater-than-page-size clusters, but that would be way more divergence-from-upstream in my source tree than I can reasonably manage. -GAWollman _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
