From: Hal Rosenstock Date: Wed, 7 Sep 2005 18:03:41 +0000 (-0700) Subject: [PATCH] IB: RMPP fixes X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b5dcbf47e10e568273213a4410daa27c11cdba3a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git [PATCH] IB: RMPP fixes - Fix payload length of middle RMPP sent segments. Middle payload lengths should be 0 on the send side. (This is perhaps a compliance and should not be an interop issue as middle payload lengths are supposed to be ignored on receive). - Fix length in first segment of multipacket sends (This is a compliance issue but does not affect at least OpenIB to OpenIB RMPP transfers).
