When compile with CONFIG_PROVE_LOCKING the following warnings happen:
[snip]
HARDIRQ-ON-W at:
[<c0480c1c>] _raw_spin_lock+0x3c/0x4c
[<c02c2828>] stmmac_set_rx_mode+0x18/0x3c

[<c038b5a8>] __dev_change_flags+0x94/0x128
[<c038b6a8>] dev_change_flags+0x10/0x48
[<c062afe0>] ip_auto_config+0x1d4/0x1084

INITIAL USE at:
[<c0480c1c>] _raw_spin_lock+0x3c/0x4c
[<c02c2828>] stmmac_set_rx_mode+0x18/0x3c
[<c038b2cc>] dev_set_rx_mode+0x1c/0x28
[<c038b38c>] __dev_open+0xb4/0xf8
[<c038b5a8>] __dev_change_flags+0x94/0x128
[<c038b6a8>] dev_change_flags+0x10/0x48
[<c062afe0>] ip_auto_config+0x1d4/0x1084
[<c000873c>] do_one_initcall+0x108/0x15c
[<c060ec50>] kernel_init_freeable+0x1a8/0x248
[<c0472cc0>] kernel_init+0x8/0x160
[<c000dfc8>] ret_from_fork+0x14/0x2c
so the patch just removes the lock protection in the stmmac_set_rx_mode
