Subject: [PATCH net 0/4] virtio_net: Make RSS interact properly with queue number
With this patch set, RSS updates with queue_pairs changing:
- When virtnet_probe, init default rss and commit
- When queue_pairs changes _without_ user rss configuration, update rss
with the new queue number
- When queue_pairs changes _with_ user rss configuration, keep rss as user
configured
Patch 1 and 2 fix possible out of bound errors for indir_table and key.
Patch 3 and 4 add RSS update in probe() and set_queues().
Please review, thanks.
Philo Lu (4):
virtio_net: Support dynamic rss indirection table size
virtio_net: Add hash_key_length check
virtio_net: Sync rss config to device when virtnet_probe
virtio_net: Update rss when set queue
