This patch supports a new fix in hardware regarding tx collisions. In the cases where we are in autoneg mode and the link partner is in forced mode, we need to setup the tx deferral register differently in order to reduce collisions on the wire. Signed-off-by:

When ARP completes due to a request rather than a reply the neighbor is marked NUD_STALE instead of reachable (see arp_process()). The handler for the resulting netevent needs to check also for NUD_STALE. Failure to use the arp entry can cause RDMA connection failures. Signed-off-by:

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). Signed-off-by:

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:

The writing of the data should implicitly truncate the data to 8bits, so do not bother with the ands in the code. Signed-off-by:

Remove the cal_CRC as this is basically wrappering the ether_crc_le function, and is only being used by the multicast hash table functions. Signed-off-by:

The code was using a delay of 8ms, when it should have been using the EEPROM status flag from the device to indicate the EEPROM transaction had finished. Signed-off-by:

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:

We have a perfectly good version control system, so we do not need to duplicate change comments in the header for this code. Signed-off-by:

Ensure we hold the spinlock whilst the registers and being modified even though we hold the overall lock. This should protect against an interrupt happening whilst we are using the device. Signed-off-by:

Remove the old hack to program an initial EEPROM setting into the DM9000 as we now have ethtool support for reading and writing the EEPROM. Signed-off-by:

Add ethtool support to access the configuration EEPROM connected to the DM9000. Signed-off-by:

Ben Dooks authored
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:

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:

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 authored
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. Signed-off-by:

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:

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 4e4fc05a 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.

1. Add common code for stopping queue. 2. No need to call netif_stop_queue followed by netif_wake_queue (and infact a netif_start_queue could have been used instead), instead call stop_queue if required, and remove code under USE_GTS macro. 3. There is no need to check for netif_queue_stopped, as the network core guarantees that for us (I am sure every driver could remove that check, eg e1000 - I have tested that path a few billion times with about a few hundred thousand qstops but the condition never hit even once).

The e1000 driver stores the content of the PCI resources into unsigned long's before ioremapping. This breaks on 32 bits platforms that support 64 bits MMIO resources such as ppc 44x. This fixes it by removing those temporary variables and passing directly the result of pci_resource_start/len to ioremap. The side effect is that I removed the assignments to the netdev fields mem_start, mem_end and base_addr, which are totally useless for PCI devices. Signed-off-by:

Add support for dual network (net_device) interface so that ethernet and wireless can own separate ethX interfaces. V2 - Fix the bug that bringing down and up the interface keeps rx disabled. - Make 'gelic_net_poll_controller()' extern , as David Woodhouse pointed out at the previous submission. - Fix weird usage of member names for the rx descriptor chain V1 - Export functions which are convenient for both interfaces - Move irq allocation/release code to driver probe/remove handlers because interfaces share interrupts. - Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb() as the interfaces share the hardware rx queue. - Add gelic_port struct in order to abstract dual interface handling - Change handlers for hardware queues so that they can handle dual {source,destination} interfaces. - Use new NAPI functions This is a prerequisite for the new PS3 wireless support.

Code cleanup: - Use appropriate prefixes for names instead of fixed 'gelic_net' so that objects of the functions, variables and constants can be estimated. - Remove definitions for IPSec offload to the gelic hardware. This functionality is never supported on PS3. - Group constants with enum. - Use bitwise constants for interrupt status, instead of bit numbers to eliminate shift operations. - Style fixes.

Mark the members of the structure for DMA descriptors with proper endian annotations and use the appropriate accessor macros. As the gelic driver works only on PS3, all these macros will be expanded to null. Signed-off-by:
