OK.
Your test program is broken; this function is missing a return
statement:
int waitForConnection(int fd) {
int cfd;
struct sockaddr_in addr;
socklen_t addrlen;
addrlen = sizeof(addr);
ioCheck(cfd = accept(fd, (struct sockaddr *)&addr, &addrlen));
}
It might be that the variable 'cfd' ends up in the return value anyway.
But you should fix this (and use compiler options -Wall and -Wextra).
The extra data at the start of 'apache.dat' and 'sendfile.dat' looks
like the packet headers, so for some reason they have been duplicated.
Please can you test the attached patch, following the instructions at
<http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>?

Subject: [PATCH] atl1c: duplicate atl1c_get_tpd
commit 678b77e265f6d66f1e68f3d095841c44ba5ab112 upstream.
remove duplicate atl1c_get_tpd, it may cause hardware to send wrong packets.
