net: hv_netvsc: reject RSS hash key programming without RX indirection table
|
|
|
|
RSS configuration requires a valid RX indirection table. When the device
|
|
reports a single receive queue, rndis_filter_device_add() does not
|
|
allocate an indirection table, accepting RSS hash key updates in this
|
|
state leads to a hang.
|
|
|
|
Fix this by gating netvsc_set_rxfh() on ndc->rx_table_sz and return
|
|
-EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device
|
|
capabilities and prevents incorrect behavior.
|
|
|
|
