Subject: [PATCH] brcmfmac: keep ARP and ND offload enabled during WOWL
|
|
|
|
Currently ARP and ND (IPv6 Neigbor Discovery) offload get disabled
|
|
on entering suspend. However when firmwares support the wowl_cap
|
|
iovar then these offload routines can be kept enabled as they
|
|
will work during WOWL as well.
