I’m probably doing something wrong (I don’t build kernels by hand very often),
but I’ve tried to apply the github code to a recent copy of head (297617) and
I’m getting errors like the following –
/usr/src/sys/dev/netmap/if_em_netmap.h:151:22: error: incompatible pointer
types initializing 'struct em_buffer *' with an expression of type 'struct
em_txbuffer *' [-Werror,-Wincompatible-pointer-types]

Any ideas or am I trying to do something stupid?

Ok, so I can assume using port names like "vale9d9af:66aa9" isn't the reason
that my test machine is panicing.
I might give 10.3 a go instead of head and see how I get on with that.
