[dpdk-dev] [PATCH] net/octeontx2: register dynamic mbuf timestamp field

[Harman Kalra <hkalra@marvell.com>]

A crash is observed if dynamic mbuf timestamp field is
registered in dev_start, as in most of the applications
rte_eth_timesync_enable is called after dev_start due
to which timestamp field did not get registered.
