Kernel 4.1.2 needs a patch for Workstation vmnet module

I'm still running Workstation 8.0.6 build-1035888 on Linux.  Specifically Fedora 22.

The recent Fedora update of kernel version 4.0.8 up to 4.1.2 rendered my kernel modules out of date and I found that vmnet would no longer compile successfully. 

The error was very similar to a previous one from an issue with kernel 3.13

/tmp/modconfig-LTmunl/vmnet-only/filter.c:206:1: error: conflicting types for ‘VNetFilterHookFn’

VNetFilterHookFn(unsigned int hooknum,                 // IN:

^

/tmp/modconfig-LTmunl/vmnet-only/filter.c:64:18: note: previous declaration of ‘VNetFilterHookFn’ was here

static nf_hookfn VNetFilterHookFn;

The following patch fixed it for me as the problem was a further change in the Linux netfilter.h file where the definition of  nf_hookfn has changed.

To apply it, copy it into a file called /root/vmnet.patch and use the following (as root) -

cd /root

mkdir vmware_modules

cp /usr/lib/vmware/modules/source/vmnet.tar /usr/lib/vmware/modules/source/vmnet.tar.orig

cp /usr/lib/vmware/modules/source/vmnet.tar vmware_modules

cd vmware_modules

tar xf vmnet.tar

patch -p 0 < /root/vmnet.patch

tar cf vmnet.tar vmnet-only

cp vmnet.tar /usr/lib/vmware/modules/source

cd /root

rm -rf vmware_modules

Then rebuild your modules as usual.
