field. The size changed at 2.6.26 from unsigned char to unsigned short.

8668b22ae8 Set max_cmd_len correctly depending on the size of the field. In earlier 
versions of Linux it was an unsigned char, and a value of 260 means 4 after a compiler warning. Added a comment to describe what is going on as well. Since 
this is done very infequently it should not cause performance problems and 
means that it will not silently fail to work if people try to use it on kernels
earlier than 2.6.26. If I figure out what kernel version the change was made
in we could use an ifdef.

5ded0b7660 Changes: 
- Implemented a workaround for a race between ib_destroy_cq() and the IB
  completion handlers. This race could trigger a kernel crash or kernel lockup
  when unloading the ib_srpt module while I/O was ongoing or by performing
  a relogin from an SRP initiator while I/O was ongoing.
- Moved the code for handling IB completions in single-threaded mode to
  separate functions.

891c7d5b03 Fix BUG while enabling target mode remote port disappear: 
In case if ELS LOGO command received on the target port,
the firmware can notify the driver about it in 3 different ways,
which handled differently by the driver (it doesn't clear when it use each way):
1. Immediate notify of login-affecting ELS command received (status code 0x46).
   The target driver terminate all commands received for the specified initiator
   (N_Port handle).
2. Asynchroneus event of port update.
   The target driver only print message, and in remark it's written that
   /* .mark_all_devices_lost() is handled by the initiator driver */
3. Immediate notify of port logged out (status code 0x29).
   The target driver terminate all commands received for the specified initiator
   (N_Port handle), and also mark all devices as lost.

In 1 and 2 everthing is OK. In 3 the target driver mark all devices as lost,
but never retrigger rescanning.

There are 2 solutions:
1. Not marking the devices as lost base on written in the async event case, and
   also base on the spec which says to only terminate all commands.
2. Mark all devices as lost and retrigger rescanning.

1 was implemented; delete all calls to mark_all_devices_lost() in qla2x00t.c, and
unexport symbol of this function in qla_os.c
