it might be fixed using the attached patch, which is MIT licensed just in

I wonder, how this could creep into the distribution, but it could also be
related to the openSUSE build, that I based my build upon (but the applied
patches doesn't appear to be guilty, AFAICS).

your patch for adding '-e' to the $(SED) command is not required here
but it's IMO more correct so I will add it to the repository.

openSUSE had a 5.0.18 in the stores, that is carrying a vbox-4.7.patch
around. After merging with 5.0.22, just one hunk was left, and that's
looking rather fishy:

Since this is not a transparent patch for kernel versions below 4.7, I
refrained from applying this at all. It bears the question though, how this
is done correctly, e.g. does 4.7 and above needs the netif_trans_update
call, 2.6.31 and below the jiffies tagging, and what to do with the kernel
versions in between.

In case, you want to peak into the build, here it is:

        
https://build.opensuse.org/package/show/home:frispete:Kernel-stable/virtual
box

The openSUSE patch is not necessary. Since 2.6.31 there is no need to update
trans_start as it is done by dev_hard_start_xmit by calling the
txq_trans_update upon device xmit callback exit.

The reason to build this package myself is due to suffering from an issue
with 5.0.18 and a bridged nic setup, that is flooding my logs with:

        VBoxNetFlt: Failed to allocate packet buffer, dropping the packet.
     Last message 'VBoxNetFlt: Failed t' repeated 196 times, suppressed by
syslog-ng

That's produced from a w2k8R2 VM on a Linux 4.2.25 host. The VM seems to
suffer under high host load. Let's see, how 5.0.22 behaves in this respect.
In case, this rings a bell for you, let me know.

Sorry, doesn't ring a bell.

In the "official" openSUSE repo, that patch is no longer applied for 5.0.22 as it was only needed for earlier versions of VB.
