Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

8 | LSI Logic Fusion(TM) Message Passing Technology (MPT) device support | ||
9 | provides high performance SCSI host initiator, and LAN [1] interface | ||
10 | services to a host system. The Fusion architecture is capable of | ||
11 | duplexing these protocols on high-speed Fibre Channel | ||
12 | (up to 2 GHz x 2 ports = 4 GHz) and parallel SCSI (up to Ultra-320) | ||

20 | default "40" | ||
21 | help | ||
22 | This option allows you to specify the maximum number of scatter- | ||
23 | gather entries per I/O. The driver defaults to 40, a reasonable number | ||
24 | for most systems. However, the user may increase this up to 128. | ||
25 | Increasing this parameter will require significantly more memory | ||
26 | on a per controller instance. Increasing the parameter is not | ||
27 | necessary (or recommended) unless the user will be running | ||
28 | large I/O's via the raw interface. | ||

32 | depends on FUSION | ||
33 | ---help--- | ||
34 | The Fusion MPT misc device driver provides specialized control | ||
35 | of MPT adapters via system ioctl calls. Use of ioctl calls to | ||
36 | the MPT driver requires that you create and use a misc device | ||
37 | node ala: | ||
38 | mknod /dev/mptctl c 10 240 | ||
39 | |||
40 | One use of this ioctl interface is to perform an upgrade (reflash) | ||
41 | of the MPT adapter firmware. Refer to readme file(s) distributed | ||
42 | with the Fusion MPT linux driver for additional details. | ||
43 | |||
44 | If enabled by saying M to this, a driver named: mptctl | ||
45 | will be compiled. | ||
46 | |||
47 | If unsure whether you really want or need this, say N. | ||

50 | tristate "Fusion MPT LAN driver" | ||
51 | depends on FUSION && NET_FC | ||
52 | ---help--- | ||
53 | This module supports LAN IP traffic over Fibre Channel port(s) | ||
54 | on Fusion MPT compatible hardware (LSIFC9xx chips). | ||
55 | The physical interface used is defined in RFC 2625. | ||
56 | Please refer to that document for details. | ||
57 | |||
58 | Installing this driver requires the knowledge to configure and | ||
59 | activate a new network interface, "fc0", using standard Linux tools. | ||
