This patch moves FRAC_PER_NS to aq_hw.h so that it can be used in both
hw_atl (A1) and hw_atl2 (A2) in the future.

I don't see this function being taken care of in the following patch
introducing the u64_stats_update_* use.
For review it'd be easier to get the existing problems fixed first.
Also since this function always returns 0 please make it void.

My bad, I totally missed this function somehow. Thanks for reporting.

Will do.

these were missing from overall stats, hardening debugging
and analysis.

This patch enables ipv6 support for TCP LSO and UDP GSO.
The code itself (aq_nic_map_skb) was ready for this after udp gso feature,
but corresponding NETIF_F_TSO6 wasn't enabled.
We now have tested both tcp and udp v6 GSO, and enabling them safely.

From: Igor Russkikh @ 2020-07-15 15:48 UTC (permalink / raw)
To: netdev; +Cc: David S . Miller, Mark Starovoytov, Jakub Kicinski, Igor Russkikh
From: Mark Starovoytov <mstarovoitov@marvell.com>
This patch adds the possibility to obtain MAC temperature via hwmon.
On A1 there are two separate temperature sensors.
On A2 there's only one temperature sensor, which is used for reporting
both MAC and PHY temperature.
