SVN rev 197787 on 2009-10-05 19:29:25Z by yongari
MFC r197461:
Use __NO_STRICT_ALIGNMENT to determine whether de(4) have to apply
alignment fixup code for received frames on strict alignment
architectures.
MFC r197463:
Consistently use bus_addr_t.
MFC r197464:
Destroy dmamap in dma cleanup.
MFC r197465:
Align Tx/Rx descriptors on 32 bytes boundary instead of PAGE_SIZE.
Also align setup descriptor on 32 bytes boundary. Tx buffer have no
alignment limitation so create dmamap without alignment
restriction[1]. Rx buffer still seems to require 4 bytes alignment
limitation but we can simply use MCLBYTES for size to map the
buffer instead of TULIP_DATA_PER_DESC as the buffer is allocated
with m_getcl(9).
de(4) supports up to TULIP_MAX_TXSEG segments for Tx buffers,
increase maximum dma segment size to TULIP_MAX_TXSEG * MCLBYTES.
While I'm here remove TULIP_DATA_PER_DESC as it is not used anymore.
This should fix de(4) breakage introduced after r176206.
