Note that netchannel does not read those ACKs sent by Linux host, since I have not completed file descriptor allocation for netchannels, so reading works only after connection has established and it is possible to bind new file descriptor to netchannel. I will resolve this issue tomorrow and will start to test alternative TCP/IP stack in userspace with netchannels. /devel/networking :: Link / Comments () |
