net: add IFF_SKB_TX_SHARED flag to priv_flags
Pktgen attempts to transmit shared skbs to net devices, which can't be used by
some drivers as they keep state information in skbs. This patch adds a flag
marking drivers as being able to handle shared skbs in their tx path. Drivers
are defaulted to being unable to do so, but calling ether_setup enables this
flag, as 90% of the drivers calling ether_setup touch real hardware and can
handle shared skbs. A subsequent patch will audit drivers to ensure that the
flag is set properly
