From: Qi Zhang Date: Thu, 21 Jan 2021 01:32:26 +0000 (+0800) Subject: net/ice/base: support configuring device in double VLAN mode X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=14e7a4b37b4f;p=dpdk.git net/ice/base: support configuring device in double VLAN mode In order to support configuring the device in Double VLAN Mode (DVM), the DDP and FW have to support DVM. If both support DVM, the PF that downloads the package needs to update the default recipes and set the VLAN mode. This is done in ice_set_dvm(). In order to support updating the default recipes in DVM add support for updating an existing switch recipe's lkup_idx and mask. This is done by first calling the get recipe AQ (0x0292) with the desired recipe ID. Then, if that is successful update one of the lookup indices (lkup_idx) and its associated mask if the mask is valid otherwise the already existing mask will be used.
