This particular commit is the start of a patches batch that ended in the generic TCP coalescing mechanism. It is known to have problem on drivers doing skb_clone() in their rx path. Current kernels should be ok, because coalescing doesnt happen if the destination skb is cloned (skb_cloned(to) in skb_try_coalesce())
The skb_clone() call is not the source of the problem for r8712u, as it is only used when a memory allocation fails, which is not happening. The suggestion did lead to another patch that I had been preparing. The initial allocation of RX buffers used a size of 30720 bytes, while 9100 is sufficient to allow aggregation. Upon reducing the buffer size, the driver now works for me. I am now awaiting tests by the OP on the Red Hat bugzilla before sending the patch upstream.
So far, no ideas for the problem in connecting to WPA1 networks. Larry -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
