From: Igor Romanov Date: Thu, 7 Feb 2019 16:29:25 +0000 (+0000) Subject: net/sfc/base: support different event descriptor sizes X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d6b55d568278316d5da6bdd66f3f8b39771d8950;p=dpdk.git net/sfc/base: support different event descriptor sizes For consistency with the size of Tx descriptors, the size of event descriptors should be a part of NIC config, not a macro that is common for all NIC families. Also, add a max number of EvQ buffers define which is needed to initialize an MCDI buffer at compile time.
