[Cbe-oss-dev] [PATCH] spidernet : fix memory leak in spider_net_stop

[Jens Osterkamp]

We forget to call spider_net_free_rx_chain_contents which does the
actual dev_kfree_skb. New skbs are allocated from skbuff_head_cache
on each "ifconfig up" letting the cache grow infinitely.

This patch fixes it.
