cxgb4: Add support for FW_ETH_TX_PKT_VM_WR
The present TX workrequest(FW_ETH_TX_PKT_WR) cant be used for host->vf communication, since it doesn't loopback the outgoing packets to virtual interfaces on the same port. This can be done using FW_ETH_TX_PKT_VM_WR. This fix depends on ethtool_flags to determine what WR to use for TX path. Support for setting this flags by user is added in next commit.
