1GbE Intel Wired LAN Driver Updates 2020-07-30

This series contains updates to e100, e1000, e1000e, igb, igbvf, ixgbe,
ixgbevf, iavf, and driver documentation.

Vaibhav Gupta converts legacy .suspend() and .resume() to generic PM
callbacks for e100, igbvf, ixgbe, ixgbevf, and iavf.

Suraj Upadhyay replaces 1 byte memsets with assignments for e1000,
e1000e, igb, and ixgbe.

Alexander Klimov replaces http links with https.

Miaohe Lin replaces uses of memset to clear MAC addresses with
eth_zero_addr().
