https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205050 --- Comment #2 from commit-hook@freebsd.org --- A commit references this bug: Author: hselasky Date: Mon Dec 14 09:46:47 UTC 2015 New revision: 292185 URL: https://svnweb.freebsd.org/changeset/base/292185 Log: MFC r291953: When setting up VLANs on a Raspberry Pi ethernet port, the MTU drops from 1500 to 1496 bytes. The MTU should remain at 1500, extending the frame size as per IEEE 802.3. Adding IFCAP_VLAN_MTU to the if_capabilities field in the smsc driver solves the problem. The datasheet for the LAN9512 chip, section 3.2.3 states that the chip supports the extended frame.
