From: Igor Romanov Date: Mon, 30 Mar 2020 10:25:44 +0000 (+0100) Subject: net/sfc/base: add API to get currently operating filters X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=db26ec5f4b3d826d39665a64ae48d5162da5e62b;p=dpdk.git net/sfc/base: add API to get currently operating filters Unknown unicast filter creation may fail because of insufficient permissions on VF. This failure is handled internally in libefx MAC reconfiguration without any way for a user to know if it happened. Making the MAC reconfiguration forward error code of filter reconfiguration would be too destructive to the existing code that may rely on the function never returning that error. Add an API for getting the status of current unknown unicast and all multicast filters since user must know that requested filters are actually applied.
