[PATCH net-next 00/12] net: stmmac: replace boolean fields in plat_stmmacenet_data with flags

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

As suggested by Jose Abreu: let's drop all 12 boolean fields in
plat_stmmacenet_data and replace them with a common bitfield.

Bartosz Golaszewski (12):
  net: stmmac: replace has_integrated_pcs field with a flag
  net: stmmac: replace the sph_disable field with a flag
  net: stmmac: replace the use_phy_wol field with a flag
  net: stmmac: replace the has_sun8i field with a flag
  net: stmmac: replace the tso_en field with a flag
  net: stmmac: replace the serdes_up_after_phy_linkup field with a flag
  net: stmmac: replace the vlan_fail_q_en field with a flag
  net: stmmac: replace the multi_msi_en field with a flag
  net: stmmac: replace the ext_snapshot_en field with a flag
  net: stmmac: replace the int_snapshot_en field with a flag
  net: stmmac: replace the rx_clk_runs_in_lpi field with a flag
  net: stmmac: replace the en_tx_lpi_clockgating field with a flag

[PATCH net-next 01/12] net: stmmac: replace has_integrated_pcs field with a flag

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

struct plat_stmmacenet_data contains several boolean fields that could be
easily replaced with a common integer 'flags' bitfield and bit defines.

Start the process with the has_integrated_pcs field.

Is that what Jose meant, or:

?

For that to work all fields would need to be gathered together (unless
the structure is __packed - not a good idea) and all future fields
would need to be added in a specific place in the structure definition
as well. I think a bit field is clearer and harder to get wrong here.
