RE: [PATCH net-next 00/10] net: l3mdev: Support for sockets bound to enslaved device

Existing code for socket lookups already pass in 6+ arguments. Rather
than add another for the enslaved device index, the existing lookups
are converted to use a new sk_lookup struct. From there, the enslaved
device index becomes another element of the struct.

Patch 1 introduces sk_lookup struct and helper.

I guess that socket lookup happens quite often!
Passing the lookup parameters in a structure might have a
measurable negative effect on performance - especially if the
structure isn't passed through to other functions.

Have you made any performance mearurements?
