| * qlcnic: Optimize MAC learning codeShahed Shaikh2014-04-27
|/ | | | | | | | | | | | * Use rx_mac_learn instead of mac_learn and eSwitch flag check in Rx path of 82xx adapter. * Check for MAC filter overrun only after driver scans through cached MAC address list. This will help to update the time stamp of cached MAC addresses even if adapter runs out of MAC address filter limit. * Remove expensive log thrown by driver when MAC address filters are exhausted Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S.

* qlcnic: Use pci_enable_msix_exact() instead of pci_enable_msix()Alexander Gordeev2014-04-27
| | | | | | | | | | | | | | | | | | As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.

* FDDI: Reformat <linux/if_fddi.h> for 8-character tabsMaciej W. Rozycki2014-04-27
| | | | | | | | | | | Some of our FDDI support code has been apparently written with an assumption that tabs are 4-character wide. In preparation to the next change this update reformats <linux/if_fddi.h> so that it stays within 79 columns and otherwise renders correctly with 8-character tabs. No functional change.

* tipc: fix a possible memory leakYing Xue2014-04-27
| | | | | | | | | | | | | | | | | | The commit a8b9b96e959f3c035af20b1bd2ba67b0b7269b19 ("tipc: fix race in disc create/delete") leads to the following static checker warning: net/tipc/discover.c:352 tipc_disc_create() warn: possible memory leak of 'req' The risk of memory leak really exists in practice. Especially when it's failed to allocate memory for "req->buf", tipc_disc_create() doesn't free its allocated memory, instead just directly returns with ENOMEM error code. In this situation, memory leak, of course, happens. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: David S.

For instance on a Leaf Light v2: --> CMD_GET_CARD_INFO <-- CMD_USB_THROTTLE <-- CMD_GET_CARD_INFO2 <-- CMD_GET_CARD_INFO_REQ When it happens, the probing function fails because we only read the first usb message. To overcome this issue, we add a mechanism of retries to the kvaser_usb_wait_msg() function. I tested this patch with the following hardware: - Kvaser Leaf Light - Kvaser Leaf Light v2 - Kvaser USBCan R This patch is necessary for the Leaf Light v2 hardware.
