Ahem... 'lspci | grep -i eth' is good but 'lspci -v' is paragraph
formatted and so finding that with grep is more trouble. You need a
"paragraph grep" of which there are many different programs and
techniques. Perl is always available these days so perhaps using perl
is easiest.
lspci -v | perl -00 -ne 'm/eth/i && print'
The extra -v information isn't usually useful though. YMMV.

Please also show us the output of
ip addr show

cat /etc/udev/rules.d/70-persistent-net.rules
