In T6, MPS classification has a 512 deep TCAM to do the match lookup. Each entry has 80x2b sets containing 48 bit MAC address, port number, VLAN Valid/ID, VNI, lookup type (outer or inner packet header). [71:48] bit locations are overloaded for outer vs. inner lookup types. Signed-off-by: NHariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The 6320 family of switch chips has a second bank for statistics, but is missing three statistics in the port registers. Generalise and extend the code: * adding a field to the statistics table indicating the bank/register set where each statistics is. * add a function indicating if an individual statistics is available on this device * calculate at run time the sset_count. * return strings based on the available statistics of the device * return statistics based on the available statistics of the device * Add support for reading from the second bank.

For unprivileged functions operations can be authorised by an admin function. Extra steps are introduced to the MCDI protocol in this situation - the initial response from the MCDI tells us that the operation has been deferred, and we must retry when told. We then receive an event telling us to retry. Note that this provides only the functionality for the unprivileged functions, not the handling of the administrative side.

Hannes points out that when we generate tcp reset for timewait sockets we pretend we found no socket and pass NULL sk to tcp_vX_send_reset(). Make it cope with inet tw sockets and then provide tw sk. This makes RSTs appear on correct interface when SO_BINDTODEVICE is used.

tcp_md5_do_lookup requires a full socket, so once we extend _send_reset() to also accept timewait socket we would have to change if (!sk && hash_location) to something like if ((!sk || !sk_fullsock(sk)) && hash_location) { ... } else { (sk && sk_fullsock(sk)) tcp_md5_do_lookup() } Switch the two branches: check if we have a socket first, then fall back to a listener lookup if we saw a md5 option (hash_location).

When closing a listen socket, tcp_abort currently calls tcp_done without clearing the request queue. If the socket has a child socket that is established but not yet accepted, the child socket is then left without a parent, causing a leak. Fix this by setting the socket state to TCP_CLOSE and calling inet_csk_listen_stop with the socket lock held, like tcp_close does. Tested using net_test. With this patch, calling SOCK_DESTROY on a listen socket that has an established but not yet accepted child socket results in the parent and the child being closed, such that they no longer appear in sock_diag dumps.

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2015-12-22 This series contains updates to fm10k only. Bruce cleans up the initialization of fm10k_workqueue at the global level, which fixes a checkpatch.pl error. Made several other cleanups of the driver, like making structures that do not change constant, remove unused code, cleanup code comments and use boolean states true/false instead of an integer since a bool is all that is needed. Jacob fixed the TLV format for little endian structures which are 4 byte aligned copy, so add an additional __aligned(4) and __packed to ensure that these structures are actually 4 byte aligned and packed correctly. Updated the driver to use ether_addr_equal() instead of memcmp() to compare MAC addresses. Alex Duyck cleans up the exception handling so all of the paths result in a similar state if we fail. Specifically the driver will now unload the mailbox interrupt, free the queue vectors and MSI-X, and then detach the interface. ==================== Signed-off-by: NDavid S.

This patch is meant to cleanup the exception handling for the paths where we reset the interrupts and then reconfigure them. In all of these paths we had very different levels of exception handling. I have updated the driver so that all of the paths should result in a similar state if we fail. Specifically the driver will now unload the mailbox interrupt, free the queue vectors and MSI-X, and then detach the interface. In addition for any of the PCIe related resets I have added a check with the hw_ready function to just make sure the registers are in a readable state prior to reopening the interface.

The TLV format for little endian structures is actually 4 byte aligned copy. To this end, we need to add an additional __aligned(4) marker along with __packed to ensure that these structures are actually 4 byte aligned and packed correctly.
