When a system has multiple ethernet devices and during DHCP request (for using NFS), the system waits only for HZ/2 which is 500mS before switching to another interface for DHCP. There are some routers (Ex: Trendnet routers) which responds to DHCP request at about 560mS. When the system has only one ethernet interface there is no issue as the timeout is 2S and the dev xid doesn't changes and only retries. But when the system has multiple Ethernet like DRA74x with CPSW in dual EMAC mode, the DHCP response is dropped as the dev xid changes while shifting to the next device. So changing inter device timeout to HZ (which is 1S). Signed-off-by:

There are two improvements in this patch: 1. Fix the build warnings; 2. Add function read_trace_pipe() to print the result on the screen; Before this patch, we can get the result through /sys/kernel/de bug/tracing/trace_pipe and get nothing on the screen. By applying this patch, the result can be printed on the screen. $ ./tracex6 ... tracex6-705 [003] d..1 131.428593: : CPU-3 19981414 sshd-683 [000] d..1 131.428727: : CPU-0 221682321 sshd-683 [000] d..1 131.428821: : CPU-0 221808766 sshd-683 [000] d..1 131.428950: : CPU-0 221982984 sshd-683 [000] d..1 131.429045: : CPU-0 222111851 tracex6-705 [003] d..1 131.429168: : CPU-3 20757551 sshd-683 [000] d..1 131.429170: : CPU-0 222281240 sshd-683 [000] d..1 131.429261: : CPU-0 222403340 sshd-683 [000] d..1 131.429378: : CPU-0 222561024 ...

This enables the use of ethtool --set-channels devname combined N to change the number of vRSS queues. Separate rx, tx, and other parameters are not supported. The maximum is rsscap.num_recv_que. It passes the given value to rndis_filter_device_add through the device_info->num_chn field. If the procedure fails, it attempts to recover to the prior state. If the recovery fails, it logs an error and aborts. Current num_chn is saved and restored when changing the MTU. Signed-off-by:

Uses device_info->num_chn to pass user provided number of vRSS queues (from ethtool --set-channels) to rndis_filter_device_add. If nonzero and less than the maximum, set net_device->num_chn to the given value; else default to prior algorithm. Always initialize struct device_info to 0, otherwise not all its fields are guaranteed to be 0, which is necessary when checking if num_chn has been purposefully set. Signed-off-by:

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: support switchdev FDB objects This patchset refactors the FDB management in the mv88e6xxx code and adds the glue in DSA to use the switchdev FDB objects. Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to br1): # bridge fdb add 3c:97:0e:11:30:6e dev swp2 # bridge fdb add 3c:97:0e:11:40:78 dev swp3 # bridge fdb add 3c:97:0e:11:50:86 dev swp4 # bridge fdb del 3c:97:0e:11:40:78 dev swp3 # bridge fdb 01:00:5e:00:00:01 dev eth0 self permanent 01:00:5e:00:00:01 dev eth1 self permanent 00:50:d2:10:78:15 dev swp0 master br0 permanent 3c:97:0e:11:30:6e dev swp2 self static 00:50:d2:10:78:15 dev swp3 master br1 permanent 3c:97:0e:11:50:86 dev swp4 self static # cat /sys/kernel/debug/dsa0/atu # DB T/P Vec State Addr # 001 Port 004 e 3c:97:0e:11:30:6e # 004 Port 010 e 3c:97:0e:11:50:86 For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for non-bridged ports and bridge groups, and the remaining will be later used by VLANs. This change is necessary to welcome the support for hardware VLANs (which will follow soon). Changes in v3: - reorder commits to improve bisectability and minimize diffs - add an ndm_state member in switchdev_fdb_obj instead of an is_static boolean - drop the need to convert unsigned char *addr to u8 addr[ETH_ALEN] (it is casted to char pointer anyway) Changes in v2: - remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code - use ether_addr_copy instead of memcpy for MAC addresses - constify MAC address in port_fdb_{add,del} - split the mv88e6xxx code refactoring into several patches ==================== Signed-off-by: -

The driver currently manages one FID per port (or bridge group), with a mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use. The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff; FID 0 means that multiple address databases are not being used). This patch changes the fid_mask for an fid_bitmap of 4096 bits. >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and bridge groups (a bridge group gets the FID of its first member). The remaining bits will be reserved for VLAN entries. Signed-off-by:

When using a cluster of switches, some topologies will have an MDIO bus per switch, not one for the whole cluster. Allow this to be represented in the device tree, by adding an optional mii-bus property at the switch level. The old platform_device method of instantiation supports this already, so only the device tree binding needs extending with an additional optional phandle. Signed-off-by:

Add an explicit neighbour table overflow message (ratelimited) and statistic to make diagnosing neighbour table overflows tractable in the wild. Diagnosing a neighbour table overflow can be quite difficult in the wild because there is no explicit dmesg logged. Callers to neighbour code seem to use net_dbg_ratelimit when the neighbour call fails which means the "base message" is not emitted and the callback suppressed messages from the ratelimiting can end-up juxtaposed with unrelated messages. Further, a forced garbage collection will increment a stat on each call whether it was successful in freeing-up a table entry or not, so that statistic is only a hint. So, add a net_info_ratelimited message and explicit statistic to the neighbour code. Signed-off-by:
