- Added debug statements to print a debug message if the MSI/MSI-X vector (or) data is zero. - This patch removes the code that will enable NAPI for the case of single ring and MSI-X / MSI case. There are some issue in the enabling NAPI with MSI/MSI-X. So we are turning off NAPI in the case of MSI/MSI-X. Signed-off-by:

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. Signed-off-by:

To Reproduce the Problem: To reproduce this panic consistently, we run an intensive network application like 'netperf' and then switch to a different console. After waiting for a couple of seconds, you will see a tx reset has occured. Reason: We enable interrupts even if we were not running. Solution: Now we will enable interrupts only after we are ready to give up the poll routine. Signed-off-by:

qla3xxx: Check return code from pci_map_single() in ql_release_to_lrg_buf_free_list(), ql_populate_free_queue(), ql_alloc_large_buffers(), and ql3xxx_send() pci_map_single() could fail. We need to properly check the return code from pci_map_single(). If we can not properly map this address, then we should cleanup and return the proper return code. Signed-off-by:

The scatter/gather lists were not being build correctly. When large frames spanned several buffers the chip would panic. Signed-off-by:

This change removes use of constants for rx buffer queue size and instead calculates the queue length based on what he MTU is set to. Signed-off-by:

This network device driver shares the same hardware as the qla4xxx iSCSI driver. Changing the MTU via the device interface will cause qla4xxx to crash as there is no way to make notification. Users wishing to change the MTU must do so using an iSCSI utility such as Qlogic SanSurfer. This forces the user to unload/reload this network device driver after the MTU value has been changed in flash. Signed-off-by:

We do not need to zero out the 64 byte MAC request I/O control block. By zeroing out the control block and setting it to proper fields is redundant work. This is because in the qla3xxx_send() function we will already set the proper fields in this structure. The unused fields are not looked at by the hardware and do not need to be zeroed out.

The return code was not properly set when when allocating memory or mapping memory failed. Depending on the stack, the return code would sometimes return 0, which indicates everything was ok, when in fact there was an error. This would cause trouble when the module was removed. Now, we will pass back the proper return code when an error occurs during the PCI probe. Signed-off-by:

The driver contains this little piece of candy: #if defined(CONFIG_DMA_NONCOHERENT) || defined(CONFIG_NOT_COHERENT_CACHE) #define ETH_DMA_ALIGN L1_CACHE_BYTES #else #define ETH_DMA_ALIGN 8 #endif Any reason why we're not using dma_get_cache_alignment() instead? Ralf Signed-off-by:

It looks like the skge driver inherited another bug from the sk98lin code. If I send from 1000mbit port to a machine on 100mbit port, the switch should be doing hardware flow control, but no pause frames show up in the statistics. This is the analog of the recent sky2 fixes. The device needs to listen for multicast pause frames and then not discard them. Signed-off-by:

It appears that under certain circumstances, a race will result in a double-free of an skb. This patch null's out the skb pointer upon the skb free, avoiding the inadvertent deref of bogus data. The next patch fixes the actual race. Signed-off-by:

As of 2.6.20-git4, the spider_net driver does not compile. This appears to be due to some archaic usage involving kobjects. It also fixes a nasty double-free during ifdown of the interface. Signed-off-by:

This version moves the medium variable to the card specific structure and changes the GMII_* to BCM54XX_* #defines. This patch adds improved version of enable_fiber for both the 5421 and the 5461 phy. It is now possible to specify with these wether you want autonegotiation or not. This is needed for bladecenter switches where some expect autonegotiation and some dont seem to like this at all. Depending on this flag it sets phy->autoneg accordingly for the fiber mode. More importantly it implements proper read_link and poll_link functions for both phys which can handle both copper and fiber mode by determining the medium first and then branching to the required functions. For fiber they all work fine, for copper they are not tested but return the result of the genmii_* function anyway which is supposed to work. The patch moves the genmii_* functions around to avoid foreward declarations. Signed-off-by:
