Add Cisco Nexus support

[GoogleCodeExporter]

Cisco Nexus series is currently unsupported. With sed I can change most of the 
problematic ace's, but it would be great if it could be included natively.

Hi,
Can you give me more details on what is different between the syntax?
I do not have a nexus device to test things out on.

Our Nexus acl's are quite simple. The differences i found until now:

- Keyword 'extended' needs to be removed
- Protocol numbers need to be replaced by their respective name (eg 6 is tcp, 
17 is udp etc)
- Only when using in switchprofile mode (in that case acl's are automatically 
distributed between multiple switches) it is necessary to number the list 
entries. But not every Nexus user uses that i guess.

A (very) simple and dirty conversion script i use at the moment:
./aclgen.py
find ./ -iname '*.acl' | while read f
do
sed  -i 's/ extended / /g' "$f"
sed  -i 's/ 6 / tcp /g' "$f"
sed  -i 's/ 17 / udp /g' "$f"
head -n 4 "$f" > "$f".head
sed '1,4d' "$f" > "$f".sed 
nl -i10 -v10 -s "  " "$f".sed | grep -v " end" >> "$f".head
rm "$f".sed
mv "$f".head "$f"
done
