Subject: [dpdk-dev] [PATCH v4 17/25] net/bnxt: modify IPV6 vtc flow field parsing
Date: Sat, 27 Jun 2020 03:00:42 -0700
Message-ID: <20200627100050.19688-18-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20200627100050.19688-1-ajit.khaparde@broadcom.com>

From: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>

ipv6 vtc_flow contains three fields
1. Version
2. Priority / Traffic Class
3. Flow Label
Currently, these are not parsed separately and also not set separately
in the field bitmap by the flow parser. However, the template treats
them separately. As a result, the flow matching doesn't succeed because
the bitmaps of parser and the template doesn't match.

This patch fixes this problem by parsing the above mentioned fields
individually to align with the template.
