Re: [Linux-ATM-General] Solos driver weirdness in bridged mode

Ok, so my previous posting fixed the preamble issue... I'm digging more into the driver and had a few more questions. First, it calls a local (static) function release_vccs(struct atm_dev *dev) but from what I can tell, this is identical to what the function atm_dev_release_vccs(struct atm_dev *dev) does in net/atm/common.c, right? The function find_vcc() is duplicated (almost verbatim) in solos-pci.c and atmtcp.c ... why not move it into atm/common.c? Getting into /proc/net/atm/ and looking at the files, I get: root@OpenWrt:/proc/1485/net/atm# pwd /proc/net/atm root@OpenWrt:/proc/1485/net/atm# head * ==> br2684<== dev nas0: num=1, mac=00:0a:fa:22:00:84 (set) vcc 0.0.35: encaps=LLC payload=bridged, failed copies 0/236 ==> devices<== Itf Type ESI/"MAC"addr AAL(TX,err,RX,err,drop) ... [refcnt] 0 solos-pci000000000000 0 ( 0 0 0 0 0 ) 5 ( 236 0 0 0 0 ) [2] 1 solos-pci000000000000 0 ( 0 0 0 0 0 ) 5 ( 0 0 0 0 0 ) [1] ==> pvc<== Itf VPI VCI AAL RX(PCR,Class) TX(PCR,Class) ==> svc<== Itf VPI VCI State Remote ==> vc<== Address Itf VPI VCI Fam Flags Reply Send buffer Recv buffer [refcnt] root@OpenWrt:/proc/1485/net/atm# so it seems that there really is something broken, at least in that the VPI/VCI failed to get plumbed if it's not showing up in the "vc" file. -Philip On 3/18/11 5:10 PM, Philip Prindeville wrote: > I'm seeing the following.
