This feature is introduced in pass-2 chip and with this CQ interrupt
coalescing will work based on both timer and count.

This adds support for offloading TCP segmentation to HW in pass-2
revision of hardware. Both driver level SW TSO for pass1.x chips
and HW TSO for pass-2 chip will co-exist. Modified SQ descriptor
structures to reflect pass-2 hw implementation.

Since we have moved on to using allocated pages to carve receive
buffers instead of netdev_alloc_skb() there is no need to store
any pointers for later retrieval. Earlier we had to store
skb and skb->data pointers which later are used to handover
received packet to netw

Call netif_carrier_on() only if interface's link is up. Switching this on
upon IFF_UP by default, is causing issues with ethernet channel bonding

Properly set CQ timer threshold and also set it to 2us.
With previous incorrect settings it was set to 0.5us which is too less.
