[PATCH AUTOSEL 4.14 41/41] net/mlx4_core: Correctly set PFC param if global pause is turned off.

[Sasha Levin]

From: Tarick Bedeir <tar...@google.com>

[ Upstream commit bd5122cd1e0644d8bd8dd84517c932773e999766 ]

rx_ppp and tx_ppp can be set between 0 and 255, so don't clamp to 1.

Fixes: 6e8814ceb7e8 ("net/mlx4_en: Fix mixed PFC and Global pause user control 
requests")
