bool "Data Center Bridging support"
default n
---help---
This enables support for configuring Data Center Bridging (DCB)
features on DCB capable Ethernet adapters via rtnetlink. Say 'Y'
if you have a DCB capable Ethernet adapter which supports this
interface and you are connected to a DCB capable switch.
DCB is a collection of Ethernet enhancements which allow DCB capable
NICs and switches to support network traffic with differing
requirements (highly reliable, no drops vs. best effort vs. low
latency) to co-exist on Ethernet.
DCB features include:
Enhanced Transmission Selection (aka Priority Grouping) - provides a
framework for assigning bandwidth guarantees to traffic classes.
Priority-based Flow Control (PFC) - a MAC control pause frame which
works at the granularity of the 802.1p priority instead of the
link (802.3x).
If unsure, say N.

A recent commit fixing DMA-buffers on stack added a shared transfer
buffer protected by a spinlock. This is broken as the USB HID request
callbacks can sleep. Fix this up by replacing the spinlock with a mutex.
