Log: vmx: fix initialization of TSO related descriptor fields Fix a mistake introduced by r343291, which ported the vmx(4) driver to iflib. In case of TSO, the hlen field of the (first) tx descriptor must be initialized to the cumulative length of Ethernet, IP and TCP headers. The length of the TCP header was missing.
