2008-02-11ixgbe: warn when device is in a x4 or lower width slotAuke Kok
It's easy to oversee this issue when working with this card as evrything will work OK but performance is severely limited (something like 1.5gbit on a x1 link) if the pci-express slot does not offer more bandwidth.

2008-02-11e1000e: Fix logic reversal keeping link activeAuke Kok
A logic mishap caused the adapter to keep link while we can disable it due to WoL not being active, and vice versa. Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11e1000: warn if this driver is used for e1000e devicesAuke Kok
We're already starting to see reports from users still using e1000 where they should be using e1000e now that this is actually possible. Just to prevent some of this thrash, add a big warning on load on these devices that people should switch to e1000e.

Code clean-up for tsi108_eth network driver. This patch removes not needed dummy read and the corresponding comment.

2008-02-11DM9000: Show the MAC address source after printing MACBen Dooks

2008-02-11DM9000: Update retry count whilst identifying chipBen Dooks
Reading the ID register does not always return the correct ID from the device, so we retry several times to see if we get a correct value. These failures seem to be excaserbated by the speed of the access to the chip (possibly time between issuing the address and then the data cycle).

2008-02-11DM9000: Add platform flag for no attached EEPROMBen Dooks
Allow the platform data to specify to the DM9000 driver that there is no posibility of an attached EEPROM on the device, so default all reads to 0xff and ignore any write operations. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Remove redudant use of "& 0xff"Ben Dooks

2008-02-11DM9000: Remove cal_CRC() and use ether_crc_le insteadBen Dooks

2008-02-11DM9000: Fix delays used by EEPROM read and writeBen Dooks

2008-02-11DM9000: Use netif_msg to enable debugging optionsBen Dooks
Use the netif_msg_*() macros to enable the debugging based on the board's msg_enable field. The output still goes via the dev_dbg() macros, so will be tagged and output as appropriate. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2008-02-11DM9000: Ensure spinlock held whilst accessing EEPROM registersBen Dooks

2008-02-11DM9000: Add mutex to protect accessBen Dooks
Add a mutex to serialise access to the chip functions from entries such as the ethtool and the MII code. This should reduce the amount of time the spinlock is held to protect the address register. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Remove barely used SROM array read.Ben Dooks
The srom array in the board data is only being used in the device probe routines. The probe also only uses the first 6 bytes of an array we spend 512ms reading 128 bytes from. Change to reading the MAC area directly to the MAC address structure. As a side product, we rename the read_srom_word to dm9000_read_eeprom to bring it into line with the rest of the driver. No change is made to the delay in this function, which will be dealt with in a later patch. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Use msleep() instead of udelay()Ben Dooks
We can use sleeping functions when reading and writing the PHY registers, so let us sleep instead of busy waiting for the PHY. Note, this also fixes a bug reading the PHY where only 100uS was being used instead of 150uS Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Do not sleep with spinlock and IRQs heldBen Dooks
The phy read and write routines call udelay() with the board lock held, and with the posibility of IRQs being disabled. Since these delays can be up to 500usec, and are only required as we have to save the chip's address register. To improve the behaviour, hold the lock whilst we are writing and then restore the state before the delay and then repeat the process once the delay has happened.

2008-02-11DM9000: Remove old timer based poll routinesBen Dooks
Remove the timer based MII phy polling, as this is currently broken with the new EEPROM code that now uses mutexes to protect the phy access. This will need to be replaced in the future by some form of mutex safe mechanism for reading the MII phy status. The replacement has not been done here as changing this patch, which is early in the sequence has quite a knock-on effect. Once this series is merged, then a new presentation of an patch to poll the MII link status can be added. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-02-11DM9000: Pass IRQ flags via platform resourcesBen Dooks
Use the flags in the IRQ resource to specify the type of IRQ being requested, so that systems which do not have level-based interrupts, or change the interrupt in some other way can specify this without making an #ifdef mess in the driver. This is specifically designed to undo the change in commit 4e4fc05a2b6e7bd2e0facd96e0c18dceb34d9349 which hardwires the type for everyone but blackfin to IRQT_RISING, which breaks all a number of Simtec boards which use (and setup in the bootloader) active low IRQs. Note, although there where originally objections due to the use of IORESOURCE_IRQ and IRQT_ flags not sharing the same definition, at least <include/linux/interrupt.h> notes these are the same.
