net : enable tx time stamping in the vde driver.

This new version moves the skb_tx_timestamp in the main uml driver. This should avoid the need to call this function in each transport (vde, slirp, tuntap, ...). It also add support for ethtool get_ts_info. Signed-off-by: Paul Chavent <[email protected]> Acked-by: Richard Cochran <[email protected]> Signed-off-by: Richard Weinberger <[email protected]>
