From: Qi Zhang Date: Tue, 10 Aug 2021 02:51:17 +0000 (+0800) Subject: net/ice/base: add timestamp masks X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=275e88b0cf1ad82f04d0cad7ba5bd893984ed4fd;p=dpdk.git net/ice/base: add timestamp masks Adding macros for shift and masking of the lower timestamp work in the Rx flex descriptor. The LSB of the timestamp-low word indicates the validity of the timestamp while the rest 7 bits contain the timestamp.
