hw/net/net_tx_pkt: Implement TCP segmentation
There was no proper implementation of TCP segmentation before this
change, and net_tx_pkt relied solely on IPv4 fragmentation. Not only
this is not aligned with the specification, but it also resulted in
corrupted IPv6 packets.
This is particularly problematic for the igb, a new proposed device
implementation; igb provides loopback feature for VMDq and the feature
relies on software segmentation.
Implement proper TCP segmentation in net_tx_pkt to fix such a scenario.
