[Xen-devel] Intel Quad NIC quirks

[Alexander Menk <alex.menk.lists2@xxxxxxxxxxxxxx>]

I added some  lines to  xend-pci-quirks.sxp in order to make the Intel
Quad NIC 82576 working. The message to check the permissive value in
syslog disappeared and I get cable connect messages inside the DomU, but
unfortunately I can not ping the device in the DomU.


Here the lspci data as requested in  xend-pci-quirks.sxp:

    (pci_config_space_fields
        # Entries are formated as follows:  
        #     <register>:<size>:<mask>
        # size is measured in bytes (1,2,4 are valid sizes)
        # mask is currently unused; use all zero's
....
         '000000a8:2:00000000'   # Intel Quad nic... no idea what
....
