Subject: ixgbe: Fix check for ixgbe_phy_x550em_ext_t reset
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5c092749e304d8b49567be633d5be31393538e3b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ixgbe: Fix check for ixgbe_phy_x550em_ext_t reset

The generic PHY reset check we had previously is not sufficient for the
ixgbe_phy_x550em_ext_t PHY type.  Check 1.CC02.0 instead - same as
ixgbe_init_ext_t_x550().
