Here is a complementary patch of the stack of RTNet for the previous patch
to work. Tested on i218V and 82579V with Xenomai 2.6.3 and Linux Kernel
3.8.13.
>From Huy-Cong Vu, Nicolas Simon
This an update of the stack of RTNet from the current (17/03/14) git dev
version of RTNet to support the latest
ethernet adapter from Intel (i217/i218). The patch for updating the rt_e1000e
driver to Kernel 3.8 version previously poste is also necessary. Tested with
i218V and 82579V.
