From: Somnath Kotur Date: Tue, 28 Jan 2020 07:29:16 +0000 (+0530) Subject: net/bnxt: fix bumping of L2 filter reference count X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9073198e42d23d00d807798e02227f7bc50a0046;p=dpdk.git net/bnxt: fix bumping of L2 filter reference count Now that the L2 filter reference count is bumped up in all cases including bnxt_alloc_filter() which is issued in init, just move this ref count bump inside the routine issuing the HWRM cmd so that it is bumped up only if the cmd is successful.
