I downloaded their driver, and compiled a new kernel without error.

Here's what I did:

# cd ~glenn
# ftp ftp://ftp.etinc.com/pub/freebsd/freebsd411_bwmgr.tgz
# gzip -d freebsd411_bwmgr.tgz
# tar xf freebsd411_bwmgr.tar
# cd usr/hdlc/dev
# cp if_etherbwmgr.c /sys/net
# cd /sys/net
# emacs files
         (added net/if_etherbwmgr.c    optional ether)
         (commented net/if_ethersubr.c
# cd /usr/src/sys/i386/conf
# GENERIC test
# emacs test
         (added options HW_WDOG)
         (added options PPP_DEFLATE)
# cd /usr/src
# make KERNCONF=test buildkernel

I don't have one of their cards, so I can't test it, but it did compile 
properly.

What were the errors you saw that prompted you to add the extra line to 
/sys/net/files ?

Neither module would load.  It fails with undefined symbols. (deflateInit_ 
for etbwmgr.ko and em_read_ctlext for etbypass.ko)

This looks like the module they supply isn't really compatible with 4.11.
