Current geneve implementation has two separate cases to handle.
1. netdev xmit
2. LWT xmit.
In case of netdev, geneve configuration is stored in various

mlx5e_xdp_set() is currently the only place where we drop reference on the
prog sitting in priv->xdp_prog when it's exchanged by a new one. We also
need to make sure that we eventually release that reference, for example,
in case the netdev is dismantled, otherwise we leak the program.
Fixes: 8699
Helpers like bpf_prog_add(), bpf_prog_inc(), bpf_map_inc() can fail
with an error, so make sure the caller properly checks their return
value and not just ignores it, which could worst-case lead to use
after free.

Sorry for the delay. Today I set up a local board to reproduce this on

Cadence GEM provides a 102 bit time counter with 48 bits for seconds,
30 bits for nsecs and 24 bits for sub-nsecs to control 1588 timestamping.
This patch does the following:
- Registers to ptp clock framework
- Timer initialization is done by writing time of day to the timer counter.
- ns increme
Hardware time stamp on the PTP Ethernet packets are received using the
SO_TIMESTAMPING API. Where timers are obtained from the PTP event/peer
registers.
