Subject: [PATCH] brcmfmac: restore stopping netdev queue when bus clogs up
|
|
MIME-Version: 1.0

|
When the host-interface bus has hard time handling transmit packets
|
|
it informs higher layer about this and it would stop the netdev
|
|
queue when needed. However, since commit 9cd18359d31e ("brcmfmac:
|
|
Make FWS queueing configurable.") this was broken. With this patch
|
|
the behaviour is restored.
