Subject: [PATCH net-next] net/sched: remove block pointer from common offload structure
From: Pieter Jansen van Vuuren <pieter.jansenvanvuuren@...ronome.com>
Based on feedback from Jiri avoid carrying a pointer to the tcf_block
structure in the tc_cls_common_offload structure. Instead store
a flag in driver private data which indicates if offloads apply
to a shared block at block binding time.
Suggested-by: Jiri Pirko <jiri@...lanox.com>

Reviewed-by: Jakub Kicinski <jakub.kicinski@...ronome.com>

Quick follow up to the series from two days ago, implementing Jiri's
suggestion. Doesn't look like the trees got merged, yet, so I'm
putting net-next in the subject 🤞
