Calls to trace incoming packets will now receive the packet context as parameter. This enables trace support for future packet types. Header trace output is in the format <field>:<value> which makes parsing easier. input_ibhdr trace before change: <idle>-0 [001] d.h. 5904.250925: input_ibhdr: [0000:05:00.0] vl 0 lver 0 sl 0 lnh 2,LRH_BTH dlid 0002 len 18 slid 0001 op 0x64,UD_SEND_ONLY se 0 m 0 pad 0 tver 0 pkey 0xffff f 0 b 0 qpn 0x000001 a 0 psn 0x000001b2 deth qkey 0x80010000 sqpn 0x000001 input_ibhdr trace after change: <idle>-0 [001] d.h. 6655.714488: input_ibhdr: [0000:05:00.0] (IB) len:124 sc:0 dlid:0x0001 slid:0x0002 lnh:2,LRH_BTH lver:0 sl:0 age:0 becn:0 fecn:0 l4:0 rc:0 entropy:0 op:0x64,UD_SEND_ONLY se:0 m:0 pad:0 tver:0 pkey:0x7fff f:0 b:0 qpn:0x000001 a:0 psn:0x00000036 hlen:8 deth qkey:0x80010000 sqpn:0x000001 Reviewed-by: Dasaratharaman Chandramouli <dasaratharaman.chandramouli@intel.com> Reviewed-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Don Hiatt <don.hiatt@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
