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 Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: Jiri Pirko <jpirko@redhat.com> CC: Robert Olsson <robert.olsson@its.uu.se> CC: Eric Dumazet <eric.dumazet@gmail.com> CC: Alexey Dobriyan <adobriyan@gmail.com> CC: David S.
