[PATCH] net: ethtool: mm: Increase FPE verification retry count

[muhammad.nazim.amirul.nazle.asmade]

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

The current FPE verification retry count is set to 3. However,
the IEEE 802.3br standard does not specify a fixed value for this.
A retry count of 3 may be insufficient when the remote device is
slow to respond during link-up. Increase the retry count to 20 to
improve robustness.
