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!

+SYSFS FILES
+
+ For each InfiniBand device, the InfiniBand drivers create the
+ following files under /sys/class/infiniband/<device name>:
+
+ node_type - Node type (CA, switch or router)
+ node_guid - Node GUID
+ sys_image_guid - System image GUID
+
+ In addition, there is a "ports" subdirectory, with one subdirectory
+ for each port. For example, if mthca0 is a 2-port HCA, there will
+ be two directories:
+
+ /sys/class/infiniband/mthca0/ports/1
+ /sys/class/infiniband/mthca0/ports/2
+
+ (A switch will only have a single "0" subdirectory for switch port
+ 0; no subdirectory is created for normal switch ports)
+
+ In each port subdirectory, the following files are created:
+
+ cap_mask - Port capability mask
+ lid - Port LID
+ lid_mask_count - Port LID mask count
+ rate - Port data rate (active width * active speed)
+ sm_lid - Subnet manager LID for port's subnet
+ sm_sl - Subnet manager SL for port's subnet
+ state - Port state (DOWN, INIT, ARMED, ACTIVE or ACTIVE_DEFER)
+ phys_state - Port physical state (Sleep, Polling, LinkUp, etc)
+
+ There is also a "counters" subdirectory, with files
+
+ VL15_dropped
+ excessive_buffer_overrun_errors
+ link_downed
+ link_error_recovery
+ local_link_integrity_errors
+ port_rcv_constraint_errors
+ port_rcv_data
+ port_rcv_errors
+ port_rcv_packets
+ port_rcv_remote_physical_errors
+ port_rcv_switch_relay_errors
+ port_xmit_constraint_errors
+ port_xmit_data
+ port_xmit_discards
+ port_xmit_packets
+ symbol_error
+
+ Each of these files contains the corresponding value from the port's
+ Performance Management PortCounters attribute, as described in
+ section 16.1.3.5 of the InfiniBand Architecture Specification.
+
+ The "pkeys" and "gids" subdirectories contain one file for each
+ entry in the port's P_Key or GID table respectively. For example,
+ ports/1/pkeys/10 contains the value at index 10 in port 1's P_Key
+ table.
+
+MTHCA
+
+ The Mellanox HCA driver also creates the files:
+
+ hw_rev - Hardware revision number
+ fw_ver - Firmware version
+ hca_type - HCA type: "MT23108", "MT25208 (MT23108 compat mode)",
+ or "MT25208"
