Mechanically substitute flags from historic mbuf allocator with malloc(9) flags in sys/dev.

MFC 232854,232874,232882,232883,232886 for bus_get_dma_tag()

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.

Consistently use bus_addr_t.

Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/

2009-06-26T11:45:06Z

IF_ADDR_UNLOCK() across network device drivers when accessing the per-interface multicast address list, if_multiaddrs. This will allow us to change the locking strategy without affecting our driver programming interface or binary interface. For two wireless drivers, remove unnecessary locking, since they don't actually access the multicast address list. Approved by: re (kib) MFC after: 6 weeks
