24 * macro Maciej W. Rozycki <macro@linux-mips.org>
40 * Adapter Probe -
45 * Bus-Specific Initialization -
46 * This driver currently supports both EISA and PCI controller
49 * initialization, the only bus-specific differences is in how the
51 * run-time critical code behaves the same on both families.
55 * Driver Open/Close -
67 * Driver Shutdown -
73 * to ensure that the adapter DMA engine is taken off-line. However,
79 * Interrupt Service Routine -
85 * Interrupt enabling/disabling can occur at many levels. At the host
87 * PIC (on Intel systems). Across the bus, both EISA and PCI adapters
88 * have a bus-logic chip interrupt enable/disable as well as a DMA
92 * bus-logic chip and assumes that Linux will take care of clearing or
93 * acknowledging any host-based interrupt chips.
95 * Control Functions -
103 * - Custom ioctl interface for executing port interface commands
104 * - Custom ioctl interface for adding unicast addresses to
105 * adapter CAM (to support bridge functions).
106 * - Custom ioctl interface for supporting firmware upgrades.
108 * Hardware (port interface) Support Routines -
110 * low-level port interface routines that are called frequently. They
113 * driver initialization and run-time code must make calls into the
114 * port interface, these routines were written to be as generic and
117 * Receive Path -
127 * single-fragment receive buffers of 4608 bytes, then allocates a
134 * Transmit Path -
142 * Before posting the buffer to the adapter, the driver sets a three-byte
153 * bytes available before the skb->data field on the outgoing transmit
155 * dev->hard_header_len to 24 bytes. 21 bytes accounts for the largest
163 * or DMAing directly from the FC byte which starts at skb->data. Should
165 * module should be updated and dev->hard_header_len should be increased.
167 * dev->hard_header_len should always be evenly divisible by 4 and at
172 * 16-Aug-96 LVS Created.
173 * 20-Aug-96 LVS Updated dfx_probe so that version information
178 * 09-Sep-96 LVS Updated dfx_ctl_set_multicast_list to enable
185 * 12-Sep-96 LVS Reset current address to factory address during
187 * single fragment which includes PRH->end of data.
189 * Jun 2000 jgarzik PCI and resource alloc cleanups
193 * Feb 2001 davej PCI enable cleanups.
