From: Thomas Monjalon Date: Sun, 25 Oct 2020 22:41:16 +0000 (+0100) Subject: net/bnxt: switch CFA code to dynamic mbuf field X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d743042821de258b8034a95530200a3a9cd59678;p=dpdk.git net/bnxt: switch CFA code to dynamic mbuf field The CFA code from mark was stored in the deprecated mbuf field udata64. It is moved to a dynamic field in order to allow removal of udata64. Note: the new field has 32 bits, smaller than udata64.
