Tushar fixes an issue which was introduced with an earlier commit, where hardware register RAR0 default MAC address does not get set properly. Alex fixes two issues, first being the VXLAN port number should be stored in network order instead of in host order. The second fix corrects the ATR code to handle IPv6 extension headers. The issue was ATR code was assuming that it would be able to use tcp_hdr for every TCP frame that came through, but that is not the case, which resulted in bad filters being setup. Mark fixes a use of usleep_range() to udelay() in the case where a lock is being held. Stefan fixes the offline self tests where ndo_stop() should be used instead of ndo_close(), which causes IFF_UP to be cleared and interface routes get removed. Emil fixes the error case where we need to return an error when a MAC address change is rejected by the PF. This helps prevent the user from modifying the MAC address when the operation is not permitted. Sridhar provides three fixes for ixgbe, all dealing with traffic class offload handling. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | * | ixgbe: Fix ATR so that it correctly handles IPv6 extension headersAlexander Duyck2016-03-291-24/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ATR code was assuming that it would be able to use tcp_hdr for every TCP frame that came through. However this isn't the case as it is possible for a frame to arrive that is TCP but sent through something like a raw socket. As a result the driver was setting up bad filters in which tcp_hdr was really pointing to the network header so the data was all invalid. In order to correct this I have added a bit of parsing logic that will determine the TCP header location based off of the network header and either the offset in the case of the IPv4 header, or a walk through the IPv6 extension headers until it encounters the header that indicates IPPROTO_TCP. In addition I have added checks to verify that the lowest protocol provided is recognized as IPv4 or IPv6 to help mitigate raw sockets using ETH_P_ALL from having ATR applied to them.

| | * | ixgbe: Store VXLAN port number in network orderAlexander Duyck2016-03-292-49/+20

This way we can avoid having to do any byte swaps in order to validate the port number. I moved the vxlan_port value into a hole in the read-mostly region of the adapter struct. This way it should be in a warm cache-line instead of in some isolated region in memory when it needs to be accessed. In addition I went through and stripped a bunch of unneeded ifdef flags since having an extra variable present doesn't really hurt anything and makes the code easier to read. I also went through and dropped the NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides no value as the flag is not evaluated in the Rx path.

Add bytes_compl local variable to __bcmgenet_tx_reclaim() to collect transmitted bytes. dev->stats updates can then be moved outside the while-loop. bytes_compl is also needed for future BQL support. 2. When bcmgenet device uses Tx checksum offload, each transmitted skb gets an extra 64-byte header prepended to it. Before this header is prepended to the skb, we need to save the skb "wire" length in GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can be done in __bcmgenet_tx_reclaim(). 3. skb->len covers the entire length of skb, whether it is linear or fragmented. Thus, when we clean the fragments, do not increase transmitted bytes.

There is one IRQ and one set of {ISR, IER, IDR, IMR} [1] registers per queue on gem hardware, though only queue0 is actually used for now to receive frames: other queues can already be used to transmit frames. The queue_readl() and queue_writel() helper macros are designed to access the relevant IRQ registers.

| * | net: hns: bug fix about getting hilink status for HNS v2Sheng Li2016-03-242-18/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hilink status reg in HNS V2 is different from HNS v1. In HNS V2, It distinguishes differnt lane status according to the bit-field of the reg. As is shown below: [0:0] ---> lane0 [1:1] ---> lane1 ... But the current driver reads the reg to get the hilink status ONLY concidering HNS V1 situation. Here is a patch to support both of them.
