Good day
I could not get help for the following error on *WRT54G*:
*root@OpenWrt:~# /etc/init.d/openflow start*
eth0.1
Configuring OpenFlow switch for out-of-band control
Jan 01 00:02:15|00001|netdev|ERR|ioctl(SIOCGIFTXQLEN) on eth0.1 device
failed: Operation not supported
*ofdatapath: failed to add port eth0.1 (Operation not supported)*
*IMPORTANT POINTS*
(i)* *I tried writing an independent program of ioctl *SIOCGIFTXQLEN *on
Linux and observed tht "Operation not supported" is observed when it is run
as normal user. As a root the program runs fine.
(ii) But i am not too sure why *ofdatapath *is throwing the error.I am
running *ofdatapath *in root login on WRT54G.
(iii) Is there a way that i can run my test ioctl program on WRT54G so that
i can debug ?
*Sample ioctl program:*
int main()
{
struct ifreq ifr;
char *ifname = "eth0";
int skfd = socket(PF_PACKET, SOCK_RAW, 0);
if( skfd < 0 )
perror("socket");
int tx_queue_len = 0;
strcpy(ifr.ifr_name, ifname);
if (ioctl(skfd, SIOCGIFTXQLEN, &ifr) < 0)
{
tx_queue_len = -1; /* unknown value */
perror("ioctl");
}
else
tx_queue_len = ifr.ifr_qlen;
printf("Q length = %d \n",tx_queue_len);
}
