Bug ID: 213845
Summary: [PATCH] bxe(4) boots with no capabilities enabled
Product: Base System
Version: 11.0-STABLE
Hardware: Any
OS: Any
Status: New
Keywords: patch
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: pher...@frenchfries.net
Keywords: patch
bxe cards boot with no hardware capabilities (i.e.
RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4...) enabled.
"ifconfig -m bxe0" correctly displays what NIC is capable of, but no options
are enabled.
This is a problem because, for example, "ifconfig vlanmtu" is not allowed to be
changed by the driver and consequently all cloned vlan devices end up with an
MTU of 1496 by default. The bug was introduced when the driver was updated to
use if_setcapabilities().
CURRENT is also affected. 10 isn't. Suggested patch against 11.0-STABLE below.
