From 490475a9938f3480e1ab3a67063e547cea41c295 Mon Sep 17 00:00:00 2001 From: Anil Veerabhadrappa Date: Thu, 8 Apr 2010 15:59:15 -0700 Subject: [SCSI] bnx2i: Bug fixes related to MTU change issue when there are active iscsi sessions bnx2i driver has to wait and cleanup all iscsi endpoints before returning from bnx2i_stop(). This is to make sure all chip resources are freed before chip is reset. As the requirements for 1G and 10G chipsets is different, added per-device 'hba_shutdown_tmo' parameter to adapter structure If the connections are not torn down by the daemon within this timeout period, 'cid's will be leaked in 10G device. 1G devices are more flexible and do not leak any resources because the whole chip ports gets reset when MTU is changed or ethtool selftest is run fixed a minor issue in bnx2i_ep_poll() which unnecessarily forced error return code when driver timed out waiting for TCP connect request to complete Signed-off-by: Anil Veerabhadrappa Reviewed-by: Mike Christie Signed-off-by: James Bottomley --- drivers/scsi/bnx2i/bnx2i.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/scsi/bnx2i/bnx2i.h') diff --git a/drivers/scsi/bnx2i/bnx2i.h b/drivers/scsi/bnx2i/bnx2i.h index 6cf9dc37d78b..6b624e767d3b 100644 --- a/drivers/scsi/bnx2i/bnx2i.h +++ b/drivers/scsi/bnx2i/bnx2i.h @@ -362,6 +362,7 @@ struct bnx2i_hba { u32 num_ccell; int ofld_conns_active; + wait_queue_head_t eh_wait; int max_active_conns; struct iscsi_cid_queue cid_que; @@ -381,6 +382,7 @@ struct bnx2i_hba { spinlock_t lock; /* protects hba structure access */ struct mutex net_dev_lock;/* sync net device access */ + int hba_shutdown_tmo; /* * PCI related info. */ -- cgit v1.2.1
