Previously we used pointer, this could have worked, because most of the time, the netmap is cached. This didn't work, however, because `lastNm` field was always nil. Rework the mechanism completely: 1. Use epoch to track netmap versions, as it it simpler and is unrelated to the TTL of an underlying cache. 2. Fix a bug where the epoch could change while mutex was unlocked. Signed-off-by: Evgenii Stratonikov <e.stratonikov@yadro.com> |
