Hi Oleg, can you try to apply this patch in this way: 1) untar netmap achive 2) dowonload linux source 3) in netmap-32e06f9d18bf/LINUX directory 3.1) ./configure --kernel-sources=/usr/src/linux-source-3.16/ --drivers=e1000e 3.2) make clean all
3.3) patch -p2 < path/to/e1000e_fix.patch 3.4) make 4) rmmod e1000e 5) insmod ./netmap.ko 6) insmod ./e1000e/e1000e.ko You must do make in LINUX dir before apply the patch and after that, you need to do again make (without clean). Tell me if it works.
