MFC r234620:

 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.
