solos: various upstreamed solos patches

These patches were submitted to netdev and will likely be out in 2.6.38.3.
In the meantime, they're needed in 2.6.37.6.

+    atm/solos-pci: Don't include frame pseudo-header on transmit hex-dump
+    
+    Omit pkt_hdr preamble when dumping transmitted packet as hex-dump;
+    we can pull this up because the frame has already been sent, and
+    dumping it is the last thing we do with it before freeing it.
+    
+    Also include the size, vpi, and vci in the debug as is done on
+    receive.
+    
+    Use "port" consistently instead of "device" intermittently.

+    atm/solos-pci: Don't flap VCs when carrier state changes
+    
+    Don't flap VCs when carrier state changes; higher-level protocols
+    can detect loss of connectivity and act accordingly. This is more
+    consistent with how other network interfaces work.
+    
+    We no longer use release_vccs() so we can delete it.
+    
+    release_vccs() was duplicated from net/atm/common.c; make the
+    corresponding function exported, since other code duplicates it
+    and could leverage it if it were public.
