Not sure whose territory this falls # in, so I'm sending it to everyone I can think of. :) # # Some time ago I did some experiments with using PPP multilink over # largish numbers of channels (up to 32). The TCP performance was # woeful due to wildly fluctuating packet latencies, which turned out to # be because we would sometimes split a packet across all 32 channels, # and sometimes we would send a whole packet down a single channel. # # This patch fixes those problems by being a bit cleverer about how the # packets are split across the available channels, and in particular, it # waits until at least half of the channels can take another fragment # before starting to split up the next packet. # # The patch also fixes a buglet in the multilink reconstruction code # where it would discard incoming packets that had just the multilink # header and no data. Such packets are valid and shouldn't be # discarded. # # Signed-off-by: Paul Mackerras # Signed-off-by: Jeff Garzik # # drivers/net/ppp_generic.c # 2005/03/29 23:37:14-05:00 paulus@samba.org +109 -66 # PPP multilink fragmentation improvements # # ChangeSet # 2005/03/30 19:43:43-05:00 linville@tuxdriver.com # [PATCH] ixgb: Add MODULE_VERSION # # Add MODULE_VERSION entry. # # Signed-off-by: John W.
