[PATCH v1 04/24] net/igc/base: increase PHY power up delay

[Anatoly Burakov]

From: Sasha Neftin <sasha.nef...@intel.com>

PHY specification for i225 requires 300 microsecond delay after power up
sequence, so increase the delay after power up to 300 microseconds.

Fixes: 8cb7c57d9b3c ("net/igc: support device initialization")
