2010-04-11[SCSI] bnx2i: Bug fixes related to MTU change issue when there are active ↵Anil Veerabhadrappa
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 <anilgv@broadcom.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

non-zero value is specified This issue was discovered during 10G iscsi testing Default value of 'sq_size' module parameter is '0' which means driver should use predefined SQ queue size when setting up iscsi connection. roundup_pow_of_two(0) results in '1' and forces driver to setup connections with send queue size of '1' and results in lower performance as well Signed-off-by: Anil Veerabhadrappa <anilgv@broadcom.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

2009-08-22[SCSI] bnx2i: register given device with cnic if shost != NULL in ep_connect()Anil Veerabhadrappa
When using iface, bnx2i was unable to offload further connections after all active sessions are logged out. bnx2i will unregister the device from cnic when the last connection is torn down. Next call to ep_connect() will fail because the device is not registered. This issue is not seen if shost == NULL is passed to ep_connect() call because in that case bnx2i will registers all known devices with cnic before doing a route look-up. When shost != NULL, bnx2i knows the device on which to offload the connection and has to register this device before attempting to offload the connection Signed-off-by: Anil Veerabhadrappa <anilgv@broadcom.com> Reviewed-by: Michael Chan <mchan@broadcom.com> Reviewed-by Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

convert bnx2i_dev_lock to type mutex from rwlock_t because cnic->register_device() can sleep for various reasons including memory allocation, waiting for ISCSI_INIT completion and while acquiring mutex lock, cnic_lock.

Fixed bnx2i_init_one() to properly handle return code of cnic->register_device() and propagate it back to the caller. No need to check for BNX2I_CNIC_REGISTERED, because unless the adapter is added to adapter_list it will not be registered in ep_connect context Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Anil Veerabhadrappa <anilgv@broadcom.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
