155  * Compute offset of port-specific register. Since there are two
156  * ports, there are two of some GEnesis modules (e.g. two sets of
157  * DMA queues, two sets of FIFO control registers, etc...). Normally,
158  * the block for port 0 is at offset 0x0 and the block for port 1 is
159  * at offset 0x80 (i.e. the next page over). However for the transmit
160  * BMUs and RAMbuffers, there are two blocks for each port: one for
161  * the sync transmit queue and one for the async queue (which we don't
162  * use). However instead of ordering them like this:
163  * TX sync 1 / TX sync 2 / TX async 1 / TX async 2
164  * SysKonnect has instead ordered them like this:
165  * TX sync 1 / TX async 1 / TX sync 2 / TX async 2
166  * This means that when referencing the TX BMU and RAMbuffer registers,
167  * we have to double the block offset (0x80 * 2) in order to reach the
168  * second queue. This prevents us from using the same formula
169  * (sk_port * 0x80) to compute the offsets for all of the port-specific
170  * blocks: we need an extra offset for the BMU and RAMbuffer registers.
171  * The simplest thing is to provide an extra argument to these macros:
172  * the 'skip' parameter. The 'skip' value is the number of extra pages
173  * for skip when computing the port0/port1 offsets. For most registers,
174  * the skip value is 0; for the BMU and RAMbuffer registers, it's 1.
