[PATCH AUTOSEL 5.6 121/606] gtp: set NLM_F_MULTI flag in gtp_genl_dump_pdp()

by Sasha Levin

From: Yoshiyuki Kurauchi <ahochauwaaaaa(a)gmail.com> [ Upstream commit 846c68f7f1ac82c797a2f1db3344a2966c0fe2e1 ] In drivers/net/gtp.c, gtp_genl_dump_pdp() should set NLM_F_MULTI flag since it returns multipart message. This patch adds a new arg "flags" in gtp_genl_fill_info() so that flags can be set by the callers. Signed-off-by: Yoshiyuki Kurauchi <ahochauwaaaaa(a)gmail.com> Signed-off-by: David S.
