[SCSI] bfa: BSG and User interface fixes. 2012-03-28T08:57:58+00:00 Krishna Gudipati kgudipat@brocade.com 2012-03-14T00:41:02+00:00 bd5a026019bc1f799065b0a39230d1f81bb4ff76 Made changes to set the rport maxfrsize param to use a value that is equal to or less than the Buffer-to-Buffer Receive Data_Field size specified in the Common Service Parameters. Increased the diag memtest timeout for the Brocade-1860 adapters. Made changes to enable valid port speed configuration check for all adapters. Made changes to increase the max hw segments in a request, in order to support larger data transfers from user space.

[SCSI] bfa: Fix to avoid vport delete hang on request queue full scenario. 2012-03-28T08:57:09+00:00 Krishna Gudipati kgudipat@brocade.com 2012-03-14T00:40:31+00:00 ff179e0f4a4da030df52c0632b0615e9a13b5e66 Fixed the LPS (Logical Port Services) state machine to send a FDISC/FLOGI to the FW from the request queue wait state, when there is space available again on the request queue. Made changes to free the vport on LOGO/cleanup complete instead of free'ing it from vport_delete_handler in the module unload scenario.
