WIZNet W5500 with additional enhancements

Fork of WIZnetInterface by WIZnet

EthernetInterface.cpp@34:7d44648ec5f2, 2017-10-09 (annotated)

Committer:
Helmut Tschemernjak
Date:
Mon Oct 09 19:58:19 2017 +0200
Revision:
34:7d44648ec5f2
Parent:
33:879cfe51e66e
Child:
35:fe3028eda085
Added support for manual DNS server config or DHCP DNS config.

Now the DNS 8.8.8.8 is only a fallback if no DNS server is specified.

Replaced error() messages with printf() to avoid hanging code in error()
