This series adds support for runtime queue count reconfiguration in the netvsc PMD, along with a prerequisite bug fix.
Patch 1 fixes a pre-existing subchannel resource leak in eth_hn_dev_uninit() where subchannels are never closed before the primary channel. Patch 2 adds runtime queue count reconfiguration via port stop/configure/start, with full NVS/RNDIS session teardown and reinit when the queue count changes. v2: - Split subchannel leak fix into separate patch with Fixes tag (patch 1) - Fix reinit_failed recovery: re-map device before chan_open when device is unmapped to prevent undefined behavior on unmapped ring buffers - Move hn_rndis_conf_offload() to after reinit block so offload config targets the final RNDIS session instead of being lost on teardown - Use write lock in hn_vf_tx/rx_queue_release() to prevent race with concurrent fast-path readers holding read lock - Reset RSS indirection table to queue 0 in subchan_cleanup error path - Fix multi-line comment style to follow DPDK convention Long Li (2): net/netvsc: fix subchannel leak on device removal net/netvsc: support runtime queue count reconfiguration drivers/net/netvsc/hn_ethdev.c | 181 +++++++++++++++++++++++++++++++-- drivers/net/netvsc/hn_vf.c | 16 +-- 2 files changed, 181 insertions(+), 16 deletions(-) -- 2.43.0
