Hi Aakash,

Thanks for your patch.

I'll leave the review of the code change itself to others,
but here is some feedback on process.

Please line-wrap patch descriptions at 75 columns wide.

Assuming this is a bug fix, a Fixes tag should be present.
It should go just before the signed-off-by line (or other tags),
with no blank lines in between.

I'm wondering if this Fixes tag is appropriate:

Fixes: 70dfe25cd866 ("net: sparx5: Update extraction/injection for timestamping")
> Signed-off-by: Aakash Menon <aakash.menon@xxxxxxxxxxxxx>

Also, for reference, fixes for Networking should, in general,
be targeted at the net tree.

And lastly, if you do post a new patch, be sure to wait 24h since
the original patch posting before doing so.
