From: Andrew Rybchenko Date: Thu, 24 Sep 2020 12:12:16 +0000 (+0100) Subject: common/sfc_efx/base: group RxQ parameters into a structure X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7640543f4c4f684dee99df343fc51403d60bd181;p=dpdk.git common/sfc_efx/base: group RxQ parameters into a structure Make number of efx_mcdi_init_rxq() arguments reasonable before addition of one more argument. Non essential parameters not supported in some cases are moved into helper structure.
