2017-04-03net: hns: Adjust the SBM module buffer thresholdKejian Yan
HNS needs SMB Buffers to store at least two packets after sending pause frame because of the link delay. The MTU of HNS is 9728. As the processor user manual described, the SBM buffer threshold should be modified.

2017-04-03net: hns: Fix to adjust buf_size of ring according to mtulipeng
Because buf_size of ring set to 2048, the process of rx_poll_one can reuse the page, therefore the performance of XGE can improve. But the chip only supports three bds in one package, so the max mtu is 6K when it sets to 2048. For better performane in litter mtu, we need change buf_size according to mtu. When user change mtu, hns is only change the desc in memory. There are some desc has been fetched by the chip, these desc can not be changed by the code. So it needs set the port loopback and send some packages to let the chip consumes the wrong desc and fetch new desc. Because the Pv660 do not support rss indirection, we need add version check in mtu change process.

A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.

2017-04-01Merge branch 'mpls-more-labels'David S. Miller
David Ahern says: ==================== net: mpls: Allow users to configure more labels per route Increase the maximum number of new labels for MPLS routes from 2 to 30. To keep memory consumption in check, the labels array is moved to the end of mpls_nh and mpls_iptunnel_encap structs as a 0-sized array. Allocations use the maximum number of labels across all nexthops in a route for LSR and the number of labels configured for LWT. The mpls_route layout is changed to: +----------------------+ | mpls_route | +----------------------+ | mpls_nh 0 | +----------------------+ | alignment padding | 4 bytes for odd number of labels; 0 for even +----------------------+ | via[rt_max_alen] 0 | +----------------------+ | alignment padding | via's aligned on sizeof(unsigned long) +----------------------+ | ... | Meaning the via follows its mpls_nh providing better locality as the number of labels increases. UDP_RR tests with namespaces shows no impact to a modest performance increase with this layout for 1 or 2 labels and 1 or 2 nexthops. mpls_route allocation size is limited to 4096 bytes allowing on the order of 30 nexthops with 30 labels (or more nexthops with fewer labels). LWT encap shares same maximum number of labels as mpls routing. v3 - initialize n_labels to 0 in case RTA_NEWDST is not defined; detected by the kbuild test robot v2 - updates per Eric's comments + added patch to ensure all reads of rt_nhn_alive and nh_flags in the packet path use READ_ONCE and all writes via event handlers use WRITE_ONCE + limit mpls_route size to 4096 (PAGE_SIZE for most arch) + mostly killed use of MAX_NEW_LABELS; it exists only for common limit between lwt and routing paths ==================== Signed-off-by: David S.

2017-04-01net: mpls: Increase max number of labels for lwt encapDavid Ahern
Alow users to push down more labels per MPLS encap. Similar to LSR case, move label array to the end of mpls_iptunnel_encap and allocate based on the number of labels for the route. For consistency with the LSR case, re-use the same maximum number of labels. Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
