           Summary: First four management packets to the card cause timeout
           Product: prim54
           Version: 1.0.2.2
          Platform: ppc
        OS/Version: Linux 2.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Device Driver
        AssignedTo: prism54-devel@prism54.org

The first four times you attempt to send a management packet to the attached
802.11g card, you get a timeout error. You may also get an "out of memory" error.

The problem occurs on a big-endian PowerPC platform.

I have found the cause of the problem. In the islpci_mgmt_rx_fill() function in
islpci_mgt.c, there are the following three lines:

frag->size = MGMT_FRAME_SIZE;
frag->flags = 0;
frag->address = buf->pci_addr;

They should read as follows:

frag->size = cpu_to_le16(MGMT_FRAME_SIZE);
frag->flags = 0;
frag->address = cpu_to_le32(buf->pci_addr);

The most likely reason this problem was not encountered before is that most
users are running this driver on the x86 platform, which is little-endian. The
above bug will only occur on a big-endian platform.
