# # IPX configuration # config IPX tristate "The IPX protocol" select LLC ---help--- This is support for the Novell networking protocol, IPX, commonly used for local networks of Windows machines. You need it if you want to access Novell NetWare file or print servers using the Linux Novell client ncpfs (available from ) or from within the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from ). In order to do the former, you'll also have to say Y to "NCP file system support", below. IPX is similar in scope to IP, while SPX, which runs on top of IPX, is similar to TCP. To turn your Linux box into a fully featured NetWare file server and IPX router, say Y here and fetch either lwared from or mars_nwe from . For more information, read the IPX-HOWTO available from . The IPX driver would enlarge your kernel by about 16 KB. To compile this driver as a module, choose M here: the module will be called ipx. Unless you want to integrate your Linux box with a local Novell network, say N. config IPX_INTERN bool "IPX: Full internal IPX network" depends on IPX ---help--- Every IPX network has an address that identifies it. Sometimes it is useful to give an IPX "network" address to your Linux box as well (for example if your box is acting as a file server for different IPX networks: it will then be accessible from everywhere using the same address). The way this is done is to create a virtual internal "network" inside your box and to assign an IPX address to this network. Say Y here if you want to do this; read the IPX-HOWTO at for details. The full internal IPX network enables you to allocate sockets on different virtual nodes of the internal network. This is done by evaluating the field sipx_node of the socket address given to the bind call. So applications should always initialize the node field to 0 when binding a socket on the primary network. In this case the socket is assigned the default node that has been given to the kernel when the internal network was created. By enabling the full internal IPX network the cross-forwarding of packets targeted at 'special' sockets to sockets listening on the primary network is disabled. This might break existing applications, especially RIP/SAP daemons. A RIP/SAP daemon that works well with the full internal net can be found on .

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
