X-Git-Tag: v2.6.19-rc3~6^2 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e8a5201506423e0241202de1349422af4260296;p=linux-2.6 [PKT_SCHED] netem: Orphan SKB when adding to queue. The networking emulator can queue SKBs for a very long time, so if you're using netem on the sender side for large bandwidth/delay product testing, the SKB socket send queue sizes become artificially larger. Correct this by calling skb_orphan() in netem_enqueue(). Signed-off-by: David S.
