Subject: [PATCH] sdk_dpaa: propagate the skb ownership information
|
|
|
|
Some skbs on the Tx path may be reallocated by the driver
|
|
due to insufficient headroom, in which case the socket
|
|
value gets lost.
|
|
|
|
Make sure we propagate the skb ownership information to the
|
|
new skb, since it's needed by the Tx timestamp function in
|
|
the kernel.
