yongari 15d9d0a9d2 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.
