Several linkmode users discard the return value of bitmap_and() and
then call linkmode_empty() on the result. Propagate the return value
through linkmode_and() and use it to avoid redundant bitmap scans.

Add bitmap_and_and() and bitmap_and_andnot() for callers that combine
three masks. The new helpers perform the operation and emptiness check
in a single pass.

Yury Norov (9):
  bitmap: add bitmap_and_and() and bitmap_and_andnot()
  linkmode: make linkmode_and() return boolean
  net: amd: xgbe: use linkmode_and() return value in
    xgbe_set_link_ksettings()
  ixgbe: use linkmode_and() return value in ixgbe_get_eee_fw()
  net: phy: use linkmode_and() return value in
    genphy_c45_eee_is_active()
  net: avoid copies before linkmode_and()
  net: phy: use linkmode operation return values in phy_device.c
  r8152: use linkmode_and_and() in EEE checks
