From adf62e83631571e74caf3d78ddb091870b9d6ecf Mon Sep 17 00:00:00 2001 From: Justin Hibbits Date: Wed, 8 Feb 2023 21:32:47 -0500 Subject: [PATCH] infiniband: Convert BPF handling for IfAPI Summary: All callers of infiniband_bpf_mtap() call it through the wrapper macro, which checks the if_bpf member explicitly. Since this is getting hidden, move this check into the internal function and remove the wrapper macro. Reviewed by: hselasky Sponsored by: Juniper Networks, Inc.
