Doing that without ntohl() is an interesting idea and it might even work occasionally; unfortunately, it's quite broken.

I fixed that and coudn't refrain from removing the most egregious warts. - mipsnet.h folded into mipsnet.c, as it doesn't provide any useful external interface. - Free SKB after transmission. - Call free_irq in mipsnet_close, to balance the request_irq in mipsnet_open. - Removed duplicate read of rxDataCount. - Some identifiers are now less verbose. - Removed dead and/or unnecessarily complex code. - Code formatting fixes. Tested on Qemu's mipssim emulation, with this patch it can boot a Debian NFSroot. Thiemo Signed-off-by: Thiemo Seufer Signed-off-by: Jeff Garzik Signed-off-by: David S.

Since the current code zeros the bonding stats when a read is requested and a pointer to that data is returned to the caller we cannot guarantee that the caller has completely accessed the data before a successive call to request the stats zeroes the stats again. This patch creates a new stack variable to keep track of the updated stats and copies the data from that variable into the bonding stats structure. This ensures that the value for any of the bonding stats should not incorrectly return zero for any of the bonding statistics. This does use more stack space and require an extra memcpy, but it seems like a fair trade-off for consistently correct bonding statistics.

The ARP monitor isn't supported for any of the bonding modes that actually require RTNL, so it is safe to not hold RTNL when failing over in the ARP monitor.

The IP Identification field can wrap around and cause data from new fragments to fill into older fragment slots with same IP Id.
