Subject: [PATCH net-next 0/6] net: restore the structure of driver-facing qcfg API

The goal of qcfg objects is to let us seamlessly support new use cases
without modifying all the drivers. We want to pull all the logic of
combining configuration supplied via different interfaces into the core
and present the drivers with a flat queue-by-queue configuration.
Additionally we want to separate the current effective configuration
from the user intent (default vs user setting vs memory provider setting).

Restructure the recently added code to re-introduce the pieces that
are missing compared to the old RFC:
https://lore.kernel.org/20250421222827.283737-1-kuba@kernel.org
Namely:
 - the netdev_queue_config() helper
 - queue config validation callback

I hopefully removed all the more "out there" parts of the RFC.

Jakub Kicinski (6):
  eth: bnxt: always set the queue mgmt ops
  net: introduce a trivial netdev_queue_config()
  net: move mp->rx_page_size validation to __net_mp_open_rxq()
  net: use netdev_queue_config() for mp restart
  net: add queue config validation callback
  eth: bnxt: plug bnxt_validate_qcfg() into qops
