I think a better fix here is to have the driver not call init_locked() when
the driver is not running when setting the MTU.
It looks like all the other Intel network drivers do the same thing as this
for the MTU.

Hi Niklaas,
Rewriting the multicast destination would be a neat trick, but sadly no.
You can't rewrite a destination address on egress. Using a route-to rule
would only modify the destination MAC address. If you were using

Regarding performance. Is it possible to get the Hyper-V to sort the
IP-packets before they enter the FreeBSD network stack in the VM?

Hello,
is it possible to configure CARP in such a way that it sends its
broadcasts on an interface different from the one that gets the shared
IP address assigned? Unfortunately, my provider blocks broadcast and
multicast on public interfaces of virtual machines.
However, they offer to set up an

Hello,
We plan to support large replay windows in the IPsec stack.
Currently, the replay window size is limited due to the size of the field used
in the sadb_sa_replay structure.

struct sadb_sa {
uint16_t sadb_sa_len;
I have two routers which have been unstable ever since I upgraded them
from 10.1 to 10.2. The symptoms were mostly livelocks, where the
machine doesn't freeze completely but is unusable (network is down,
console doesn't refresh, it seems to react to keyboard input and tries

version of Netmap :
