Bryan Venteicher 443c3d0bd1 Do not place the sglist used for Rx/Tx on the stack ... The sglist segment array has grown to a bit over 512 bytes (on 64-bit system) which is more than ideally should be put on the stack. Instead allocate an appropriately sized sglist and hang it off each Rx/Tx queue structure. Bump the maximum number of Tx segments to 64 to make it unlikely we'll have defragment an mbuf chain. Our previous count was rounded up to this value since it is the next power of two, so effective memory usage should not change. Also only allocate the maximum number of Tx segments if TSO was negotiated.		2014-02-02 05:15:36 +00:00
