During a dump, this attribute is essential, it enables the userspace to know on which interface the context is linked to. Fixes: 459aa660eb1d ("gtp: add initial driver for datapath of GPRS Tunneling Protocol (GTP-U)") Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Tested-by: Gabriel Ganne <gabriel.ganne@6wind.com> --- I target this to net, because I think this is a bug fix. The dump result cannot be used if there is more than one gtp interface on the system. drivers/net/gtp.c | 1 + 1 file changed, 1 insertion(+)
