Subject: [PATCH v2 net-next 00/16] sfc: prerequisites for EF100 driver, part 3

Continuing on from [1] and [2], this series assembles the last pieces
 of the common codebase that will be used by the forthcoming EF100
 driver.
Patch #1 also adds a minor feature to EF10 (setting MTU on VFs) since
 EF10 supports the same MCDI extension which that feature will use on
 EF100.
Patches #5 & #7, while they should have no externally-visible effect
 on driver functionality, change how that functionality is implemented
 and how the driver represents TXQ configuration internally, so are
 not mere cleanup/refactoring like most of these prerequisites have
 (from the perspective of the existing sfc driver) been.

Changes in v2:
* Patch #1: use efx_mcdi_set_mtu() directly, instead of as a fallback,
  in the mtu_only case (Jakub)
* Patch #3: fix symbol collision in non-modular builds by renaming
  interrupt_mode to efx_interrupt_mode (kernel test robot)
* Patch #6: check for failure of netif_set_real_num_[tr]x_queues (Jakub)
* Patch #12: cleaner solution for ethtool drvinfo (Jakub, David)

Edward Cree (16):
  sfc: support setting MTU even if not privileged to configure MAC fully
  sfc: remove max_interrupt_mode
  sfc: move modparam 'interrupt_mode' out of common channel code
  sfc: move modparam 'rss_cpus' out of common channel code
  sfc: make tx_queues_per_channel variable at runtime
  sfc: commonise netif_set_real_num[tr]x_queues calls
  sfc: assign TXQs without gaps
  sfc: don't call tx_limit_len if NIC type doesn't have one
  sfc: factor out efx_mcdi_filter_table_down() from _remove()
  sfc: commonise efx_fini_dmaq
  sfc: initialise RSS context ID to 'no RSS context' in
    efx_init_struct()
  sfc: get drvinfo driver name from outside the common code
  sfc_ef100: add EF100 to NIC-revision enumeration
  sfc_ef100: populate BUFFER_SIZE_BYTES in INIT_RXQ
  sfc_ef100: NVRAM selftest support code
  sfc_ef100: helper function to set default RSS table of given size
