​The kmod-forcedeth package was rebuilt against the EL7.4 kernel (​

lrepo.x86_64.rpm

Or other mirror sites. Can you run a test? Please note that this is not
backward compatible with earlier (<= 7.3) kernels.

Okay, I have installed it and it works.

# uname -r
3.10.0-693.el7.x86_64

# rpm -q kmod-forcedeth
kmod-forcedeth-0.64-3.el7.elrepo.x86_64

# ethtool -i net0
driver: forcedeth
version: 0.64
firmware-version: expansion-rom-version: bus-info: 0000:00:0a.0

supports-test: yes
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

Note that one must be a bit careful, since you first must install the
new kernel, and only then can you install this kmod-forcedeth driver because
of dependencies on the kabi framework.

The new kmod driver 'updates' the old one, all your old forcedeth modules
disappear (because it is incompatible with older kernels?).

This means you cannot boot back to older kernels and still have a functional network.
