The change was merged with r235527 by jfv and was: If we pass down 64k - L2 hdr size + 1 to 64K L3+ data adding an ether header will make the data go over the 64k limits announced to busdma as maxsize and the transaction will fail. With TSO this can result in a TCP regression due to the lost packet. According to the data sheets ixgbe(4) 82598 and 82599 can handle up to 256k so increase the maximum. Reported by: Jon Kåre Hellan, UNINETT (jon.kare.hellan uninett.no) Tested by: Jon Kåre Hellan, UNINETT (jon.kare.hellan uninett.no) Just the merge-info was missing on stable/9. > Modified: > Directory Properties: > stable/9/sys/ (props changed) -- Bjoern A.
