[PATCH RFC 0/4] net: ipa: add support for Eliza SoC (IPA 5.5)

[Alexander Koskovich]

This series adds support to the IPA driver for the Eliza SoC (IPA 5.5).

Wanted some feedback on how best to handle the difference in the Q6 FNR
counters between Eliza & SM8550/SM8650, since it also changes the memory
layout [1].

I was thinking about something like checking firmware version after
loading IPA firmware and if above X version, use increased FnR counters
but I am not sure what firmware version this was introduced in.

For now I am just doing it with a seperate Eliza compatible but this
feels kind of meh. I'm also not sure if it's possible there's some Eliza
variant out there that actually has firmware that is too old, and then
68 for FnR counters is too much.

I also wanted some clarification on the general need to pass hw filter
stats info, downstream this is marked as "optional", but seems very
much needed for Eliza.

Is this actually optional and there is just some other misconfiguration
or is firmware broken? Hard to debug what modem wants since system does
a complete halt shortly after starting IPA if I don't pass this.
