Zeeb <bz@FreeBSD.org> CommitDate: 2023-11-17 12:17:54 +0000 dpaa2: make software VLANs usable on dpni dpni announces IFCAP_VLAN_MTU but internally does not increase the maximum frame length. Createing a vlan interface on top of a dpni interface will result in full-sized frames not passing. Extend the maximum frame length by ETHER_VLAN_ENCAP_LEN to allow at least for one layer of (software) vlans for now MFC after: 3 days GH-Issue: https://github.com/mcusim/freebsd-src/issues/22 Reviewed by: dsl Differential Revision: https://reviews.freebsd.org/D42645 --- sys/dev/dpaa2/dpaa2_ni.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sys/dev/dpaa2/dpaa2_ni.c b/sys/dev/dpaa2/dpaa2_ni.c index 7cb472f45ee4..b274d5670d5f 100644 --- a/sys/dev/dpaa2/dpaa2_ni.c +++ b/sys/dev/dpaa2/dpaa2_ni.c @@ -2556,7 +2556,7 @@ dpaa2_ni_ioctl(if_t ifp, u_long c, caddr_t data) /* Update maximum frame length. */ error = DPAA2_CMD_NI_SET_MFL(dev, child, &cmd, - mtu + ETHER_HDR_LEN); + mtu + ETHER_HDR_LEN + ETHER_VLAN_ENCAP_LEN); if (error) { device_printf(dev, "%s: failed to update maximum frame " "length: error=%d\n", __func__, error);
