Subject: [PATCH] mac80211: check per vif offload_flags in Tx path
|
|
|
|
offload_flags has been introduced to indicate encap status of each interface.
|
|
An interface can encap offload at runtime, or if it has some extra limitations
|
|
it can simply override the flags, so it's more flexible to check offload_flags
|
|
in Tx path.
