2007-10-10[NET] drivers/net: statistics cleanup #1 -- save memory and shrink codeJeff Garzik
We now have struct net_device_stats embedded in struct net_device, and the default ->get_stats() hook does the obvious thing for us. Run through drivers/net/* and remove the driver-local storage of statistics, and driver-local ->get_stats() hook where applicable. This was just the low-hanging fruit in drivers/net; plenty more drivers remain to be updated.

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger
Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted.

2007-03-28qla3xxx: bugfix: Jumbo frame handling.Ron Mercer
Fixed rx checksum bits. Turn on TCP processing for rx checksum. Fixed max frame length register write. It wasn't getting set in multi-port system. Set rx buffer queue length properly for jumbo frames. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-27qla3xxx: Kernic Panic on pSeries under stress conditionsBenjamin Li
To reproduce this panic consistently, we run an intensive network application like 'netperf'. After waiting for a couple of seconds, you will see a stack trace and a kernel panic where we are calling pci_unmap_single() in ql_poll(). Changes: 1) Check the flags on the Response MAC IO Control block to check for errors 2) Ensure that if we are on the 4022 we only use one segment 3) Before, we were reading the memory mapped producer index register everytime we iterated in the loop when clearing the queue. We should only be iterating to a known point, not as the producer index is being updated.

2006-07-29[PATCH] qla3xxx NIC driverRon Mercer
This is a complementary network driver for our ISP4XXX parts. There is a concurrent effort underway to get the iSCSI driver (qla4xxx) integrated upstream as well. I have been through several iterations with the linux-netdev list and have had much response from Stephen Hemminger. - Built and tested using kernel 2.6.17-rc4. - The chip supports two ethernet and two iSCSI functions. - The functions ql_sem_lock, ql_sem_spinlock, ql_sem_unlock, and ql_wait_for_drvr_lock are used to protect resources that are shared across the network and iSCSI functions. This protection is mostly during chip initialization and resets, but also include link management. - The PHY/MII are not exported through ethtool due to the fact that the iSCSI function will control the common link at least 50% of the time. This driver has been through several iterations on the netdev list and we feel this driver is ready for inclusion in the upstream kernel. It has been built and tested on x86 and PPC64 platforms.
