Subject: net/i40e: fix time sync for 25G
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d9263ab13886f8b25a324e40ddb205f1a3f71c6d;p=dpdk.git

net/i40e: fix time sync for 25G

Time sync increment value is not configured for 25G device.

The patch fix this issue by setting the same value as 40G, this
aligned with kernel driver's behaviour.

Fixes: 75d133dd3296 ("net/i40e: enable 25G device")
