net: amd: fix return type of ndo_start_xmit function

2019-11-25T14:54:05Z

[ Upstream commit fe72352e37ae8478f4c97975a9831f0c50f22e73 ] The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, so make sure the implementation in this driver has returns 'netdev_tx_t' value, and change the function return type to netdev_tx_t.

net: fix amd-xgbe flow-control issue

2018-08-06T14:24:40Z

[ Upstream commit 7f3fc7ddf719cd6faaf787722c511f6918ac6aab ] If we enable or disable xgbe flow-control by ethtool , it does't work.Because the parameter is not properly assigned,so we need to adjust the assignment order of the parameters.

amd-xgbe: Check xgbe_init() return code

2017-07-05T12:37:19Z

[ Upstream commit 738f7f647371ff4cfc9646c99dba5b58ad142db3 ] The xgbe_init() routine returns a return code indicating success or failure, but the return code is not checked. Add code to xgbe_init() to issue a message when failures are seen and add code to check the xgbe_init() return code. Signed-off-by: Tom Lendacky Signed-off-by: David S.

amd-xgbe: Fix jumbo MTU processing on newer hardware

2017-03-30T07:35:13Z

[ Upstream commit 622c36f143fc9566ba49d7cec994c2da1182d9e2 ] Newer hardware does not provide a cumulative payload length when multiple descriptors are needed to handle the data. Once the MTU increases beyond the size that can be handled by a single descriptor, the SKB does not get built properly by the driver. The driver will now calculate the size of the data buffers used by the hardware. The first buffer of the first descriptor is for packet headers or packet headers and data when the headers can't be split. Subsequent descriptors in a multi-descriptor chain will not use the first buffer. The second buffer is used by all the descriptors in the chain for payload data. Based on whether the driver is processing the first, intermediate, or last descriptor it can calculate the buffer usage and build the SKB properly. Tested and verified on both old and new hardware.

amd-xgbe: fix a couple timeout loops

2015-12-15T17:43:01Z

At the end of the loop we test "if (!count)" but because "count--" is a post-op then the loop will end with count set to -1. I have fixed this by changing it to --count. Fixes: c5aa9e3b8156 ('amd-xgbe: Initial AMD 10GbE platform driver') Signed-off-by: Dan Carpenter Signed-off-by: David S. Miller

amd-xgbe: Fix race between access of desc and desc index

2015-10-28T02:49:22Z

During Tx cleanup it's still possible for the descriptor data to be read ahead of the descriptor index. A memory barrier is required between the read of the descriptor index and the start of the Tx cleanup loop. This allows a change to a lighter-weight barrier in the Tx transmit routine just before updating the current descriptor index. Since the memory barrier does result in extra overhead on arm64, keep the previous change to not chase the current descriptor value. This prevents the execution of the barrier for each loop performed. Suggested-by: Alexander Duyck Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller
