net: mscc: ocelot: extract ocelot_xmit_timestamp() helper

Browse source

[ Upstream commit 29372f07f7 ]

Extract the PTP timestamp handling logic from ocelot_port_xmit() into a
separate ocelot_xmit_timestamp() helper function. This is a pure
refactor with no behavioral change.

The helper returns false if the skb was consumed (freed) due to a
timestamp request failure, and true if the caller should continue with
frame injection. The rew_op value is returned via pointer.

This prepares for splitting ocelot_port_xmit() into separate FDMA and
register injection paths in a subsequent patch.
