From: Yong Xu <[email protected]>
Correct calculation of burst parameter used when configuring TC policer
action for ingress port-based policing in the case where TC offload is in
use. This now matches the value calculated for the case where TC offload is
not in use.
The division by 8 is to convert from bits to bytes.
Its unclear why 64 was previously used.
Fixes: e7f6ba220 ("lib/tc: add ingress ratelimiting support for tc-offload")
