Hello there,
I just tried to compile the Linux Kernel version 2.6.11.12
with the gcc 4.0 compiler. The compiler said
drivers/net/depca.c:1829: warning: operation on 'i' may be undefined
The source code is
for (i = entry; i != end; i = (++i) & lp->txRingMask) {
I agree with the compiler. Better code is
for (i = entry; i != end; i = (i + 1) & lp->txRingMask) {
Regards
David Binderman

Someone already fixed it.
/* set up the buffer descriptors */
len = (skb->len < ETH_ZLEN) ? ETH_ZLEN : skb->len;
for (i = entry; i != end; i = (i+1) & lp->txRingMask) {
