Commit Message

Michal Swiatkowski May 7, 2024, 11:45 a.m. UTC 
Store subfunction and VF pointer in port representor structure as an
union. Add port representor type to distinguish between each of them.

Keep the same flow of port representor creation, but instead of general
attach function create helpers for VF and subfunction attach function.

Type of port representor can be also known based on VSI type, but it
is more clean to have it directly saved in port representor structure.

Create port representor when subfunction port is created.

Add devlink lock for whole VF port representor creation and destruction.
It is done to be symmetric with what happens in case of SF port
representor. SF port representor is always added or removed with devlink
lock taken. Doing the same with VF port representor simplify logic.

This calls for a split to at least 2 patches. One patch to prepare and
one to add the SF support?

Is 187 insertions and 80 deletions too many for one patch? Or the
problem is with number of files changed?

I don't see what here can be moved to preparation part as most changes
depends on each other. Do you want me to have one patch with unused
functions that are adding/removing SF repr and another with calling
them?

Thanks,
Michal

The patch is hard to follow, that's the problem.

Ok, I will do my best to make it easier to read in next version.
