net/dcb: Add IEEE QCN attribute

2015-03-07T02:50:02Z

As specified in 802.1Qau spec. Add this optional attribute to the DCB netlink layer. To allow for application to use the new attribute, NIC drivers should implement and register the callbacks ieee_getqcn, ieee_setqcn and ieee_getqcnstats. The QCN attribute holds a set of parameters for management, and a set of statistics to provide informative data on Congestion-Control defined by this spec.

Update setapp/getapp prototypes in dcbnl_rtnl_ops to return int instead of u8

2014-07-17T23:02:29Z

v2: fixed issue with checking return of dcbnl_rtnl_ops->getapp() Signed-off-by: Anish Bhatt Signed-off-by: David S. Miller

include/net/: Fix FSF address in file headers

2013-12-06T17:37:56Z

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes. Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

net/dcb: Add an optional max rate attribute

2012-04-05T09:08:04Z

Although not specified in 8021Qaz spec, it could be useful to enable drivers whose HW supports setting a rate limit for an ETS TC. This patch adds this optional attribute to DCB netlink. To use it, drivers should implement and register the callbacks ieee_setmaxrate and ieee_getmaxrate. The units are 64 bits long and specified in Kbps to enable usage over both slow and very fast networks. Signed-off-by: Amir Vadai Signed-off-by: David S. Miller

net: dcb: getnumtcs()/setnumtcs() should return an int

2012-03-03T02:16:49Z

{g|s}etnumtcs() today returns a u8 that is only used by the DCB code to verify no error occurred. Today the driver implementations return negative error codes which end up being non-zero so the logic works out but triggers some sparse warnings. To fix the sparse warnings convert the return value to an int. CC: Eilon Greenstein Reported-by: Dan Carpenter Signed-off-by: John Fastabend Tested-by: Ross Brattain Signed-off-by: Jeff Kirsher

dcb: add DCBX mode to event notifier attributes

2011-10-06T19:49:51Z

Add DCBX mode to event notifiers so listeners can learn currently enabled mode. Signed-off-by: John Fastabend Signed-off-by: David S. Miller

dcb: Use ifindex instead of ifname

2011-10-06T19:49:51Z

Use ifindex instead of ifname in the DCB app ring. This makes for a smaller data structure and faster comparisons. It also avoids possible issues when a net device is renamed. Signed-off-by: Mark Rustad Signed-off-by: John Fastabend Signed-off-by: David S. Miller

dcbnl: Add CEE notification

2011-07-06T06:42:17Z

This patch add an unsolicited notification of the DCBX negotiated parameters for the CEE flavor of the DCBX protocol. The notification message is identical to the aggregated CEE get operation and holds all the pertinent local and peer information. The notification routine is exported so it can be invoked by drivers supporting an embedded DCBX stack. Signed-off-by: Shmulik Ravid Signed-off-by: David S. Miller

dcb: fix return type on dcb_setapp()

2011-06-21T23:06:12Z

Incorrect return type on dcb_setapp() this routine returns negative error codes. All call sites of dcb_setapp() assign the return value to an int already so no need to update drivers. Signed-off-by: John Fastabend Signed-off-by: David S. Miller

dcb: Add dcb_ieee_getapp_mask() for drivers to query APP settings

2011-06-21T23:06:12Z

With multiple APP entries per selector and protocol drivers or stacks may want to pick a specific value or stripe traffic across many priorities. Also if an APP entry in use is deleted the stack/driver may want to choose from the existing APP entries. To facilitate this and avoid having duplicate code to walk the APP ring provide a routine dcb_ieee_getapp_mask() to return a u8 bitmask of all priorities set for the specified selector and protocol. This routine and bitmask is a helper for DCB kernel users. Signed-off-by: John Fastabend Signed-off-by: David S. Miller
