X-Git-Tag: omap-for-v4.2/o2_dc~58^2~2 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=71cd26e76a9514715df7880db0a8f7c37c17149a;p=pandora-kernel.git altera tse: Error-Bit on tx-avalon-stream always set. The Error-Bit on the avalon streaming interface of the tx-dma-channel was always set. In SGMII configurations this leads to error-symbols on the PCS and packet-rejection on the receiver side (e.g. SGMII/1000Base-X connected switch). This only applies to the tse-configuration with MSGDMA. This issue was detected and fixed on a custom board with a direct connection to a Marvell switch in SGMII-PHY-Mode. (incl. custom patches for SGMII-PCS). According to the datasheet if ff_tx_err (avalon-streaming) is set it is forwarded to gm_tx_err. As a result the PCS is forwarding the error by sending a "/V/"-caracter. Signed-off-by: Andreas Oetken Signed-off-by: David S. Miller --- Reading git-diff-tree failed
