From: Nazim Amirul <muhammad.nazim.amirul.nazle.asmade at altera.com>

Three fixes for the stmmac FPE implementation:

- Keep pmac_enabled true in DWMAC since the preemptive MAC is always
  on, enforce this in set_mm(), and guard set_mm() with fpesel check
- Fix missing return in stmmac_fpe_init() when FPE is unsupported
- Move fprq configuration to stmmac_fpe_configure_pmac() where it
  belongs

v2:
  - Drop u32_replace_bits() in patch 3; fprq_mask is not a compile-time
    constant and triggered __bad_mask on x86 builds. Keep the open-coded
    mask/shift update instead.
  - Collect Reviewed-by from Maxime Chevallier.

Nazim Amirul (3):
  net: stmmac: fpe: Enforce pmac_enabled in set_mm and keep it on at
    init
  net: stmmac: fpe: Add missing return in stmmac_fpe_init()
  net: stmmac: fpe: Move fprq configuration to
    stmmac_fpe_configure_pmac()
