2009-07-10cxgb3: Fix crash caused by stashing wrong netdev_queueRoland Dreier
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

2009-05-29cxgb3: fix dma mapping regressionDivy Le Ray
Commit 5e68b772e6efd189d6aca76f6872fb75d51ace60 cxgb3: map entire Rx page, feed map+offset to Rx ring. introduced a regression on platforms defining DECLARE_PCI_UNMAP_ADDR() and related macros as no-ops. Rx descriptors are fed with the a page buffer bus address + page chunk offset. The page buffer bus address is set and retrieved through pci_unamp_addr_set(), pci_unmap_addr(). These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

2009-04-20cxgb3: fix workqueue flush issuesDivy Le Ray
The fatal error task can be scheduled while processing an offload packet in NAPI context when the connection handle is bogus. this can race with the ports being brought down and the cxgb3 workqueue being flushed. Stop napi processing before flushing the work queue. The ULP drivers (iSCSI, iWARP) might also schedule a task on keventd_wk while releasing a connection handle (cxgb3_offload.c::cxgb3_queue_tid_release()). The driver however does not flush any work on keventd_wq while being unloaded. This patch also fixes this. Also call cancel_delayed_work_sync in place of the the deprecated cancel_rearming_delayed_workqueue. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
