Subject: [PATCH AUTOSEL 5.13 115/189] net: hsr: don't check sequence number if tag removal is offloaded
From: George McCollister <george.mccollister@...il.com>
[ Upstream commit c2ae34a7deaff463ecafb7db627b77faaca8e159 ]
Don't check the sequence number when deciding when to update time_in in
the node table if tag removal is offloaded since the sequence number is
part of the tag. This fixes a problem where the times in the node table
wouldn't update when 0 appeared to be before or equal to seq_out when
tag removal was offloaded.
