Hi!
Why if_vlan allow to set same MTU size or bigger as on parrent nic?
Setup:
- workstation with MTU 9000 and IPv4 on h/w nic
- server with MTU 9000 on h/w nic and IPv4 on vlan nic with MTU 9000 (set by
defauil on iface creation)
This setup have issue:
- big packets from server->wks - OK

Hi!
I have strange case: FreeBSD 12.2 ignore TCP RST from windows host and continue
retransmitting packets.
sockstat show that socket connected even after many tcp rst packets received.
Any ideas how to fix it?

Hi!
I have FreeBSD 13@amd64 router with DHCP client on uplink.
How to run script on IP address change?
I do not see events from devd, only:
!system=IFNET subsystem=em3 type=LINK_DOWN
!system=IFNET subsystem=em3 type=LINK_UP

Hi!
For peoples who want to use linux WiFi drivers on FreeBSD with minimum support
overhead :)
This "how-to" (draft) describes how to use OpenWRT as driver with web GUI for
WiFi adapters.
No more pain with slow speed, no strange wpa_supplicant gui tools :)
This upgrades WiFi speed from

Hi!
if_lagg together with two multicast igb at more than 100 megabits led
to 100% CPU interrupts one of the igb.
The problem is not reproduced on other systems without igb adapters.
So I gathered on lagg netgraph and with him there is no problem.
