libdnet when we can instead of our own home grown stuff.
SConscript:
separate the crc code into its own file
base/inet.cc:
move the crc stuff to crc.cc
add generic code for calculating ip/tcp/udp checksums
base/inet.hh:
- move crc stuff to crc.hh
- #include all of the libdnet stuff. (this makes base/inet.hh the
only file you need to include if you want to use this kind of stuff.)
- Wrap some of the libdnet structs to get easier access to structure
members. These wrappers will automatically deal with masking/shifting/
byte-swapping.
base/refcnt.hh:
If one derives from RefCountingPtr, they should have access to
the internal data pointer.
build/SConstruct:
make #include of dnet stuff work
dev/etherlink.cc:
dev/ethertap.cc:
dev/ethertap.hh:
EtherPacket -> PacketData
dev/etherpkt.cc:
EtherPacket -> PacketData
add a function for populating extra info about a packet.
Basically just gives pointers to ethernet/ip/tcp/udp headers
if they exist.
dev/etherpkt.hh:
EtherPacket -> PacketData
remove most of the packet header stuff from teh PacketData
class and just add a few generic functions for grabbing various
headers that may exist in the packet. The old functionality is
contained in the headers.
dev/ns_gige.cc:
- IP -> Ip, UDP -> Udp, TCP ->Tcp when used in variable names
- get rid of our own byte swapping functions.
- whack checksum code and use libdnet version.
- Get pointers to the various packet headers and grab info from
those headers. (The byte swapping in the headers now.)
- Add stats for Udp Checksums
dev/ns_gige.hh:
use libdnet for checksum code.
IP -> Ip, TCP -> Tcp in variable names
add stats for UDP checksums
