2006-11-17Add a lower TX threshold value and use this when checking the number ofBrad Smith
available TX descriptors in the case that em_encap() has tried to reclaim descriptors. From Jack Vogel@Intel Tested by brad@, mk@, Gabriel Kihlman <gk at stacken dot kth dot se>, Johan Mson Lindman <tybollt at solace dot mh dot se> Tested on amd64/i386/sparc64
2006-11-14Rework the transmit register handling. In em_encap() store the index ofBrad Smith
the EOP descriptor in the first descriptor of the packet. In em_txeof() search for the DD bit set only in the EOP descriptors, embedding the cleanup of all packet's descriptors into the inner loop. This change is important for future chips, where the DD bit is going to be set only in the EOP descriptors. From Jack Vogel@Intel Tested by brad@, mk@, reyk@, Gabriel Kihlman <gk at stacken dot kth dot se>, Johan Mson Lindman <tybollt at solace dot mh dot se>, Jason Dixon and a few others. Tested on i386/amd64/sparc64.

2006-11-07em_get_buf():Brad Smith
- Use bus_dmamap_load_mbuf() instead of bus_dmamap_load() + mtod(). - Only BUS_DMASYNC_PREREAD is necessary for the bus_dmamap_sync(). em_allocate_receive_structures(): - Clean up error handling for receive buffer allocation and just have everything done by em_free_receive_structures() now. em_free_receive_structures(): - A few changes here to allow this function to be called from em_stop() as well as em_allocate_receive_structures(). Tested on i386/amd64/sparc64. ok reyk@
2006-11-06Sync up to Intel's latest FreeBSD em driver (6.2.9). Adds supportBrad Smith
for a few newer Intel PCIe boards, some code removal and cleaning and a few bug fixes. From: Jack Vogel@Intel Tested by mk@ wilfried@ brad@ dlg@, Marc Winiger, Gabriel Kihlman, Jason Dixon, Johan Mson Lindman, and a few other end users. Tested with 82543, 82544, 82540, 82545, 82541, 82547, 82546 and 82573.

2006-09-17Overhaul RX path to recover from mbuf cluster allocation failure.Brad Smith
- Create a spare DMA map for RX handler to recover from bus_dmamap_load() failure. - Make sure to update status bit in RX descriptors even if we failed to allocate a new buffer. - Don't blindly unload DMA map. Reuse loaded DMA map if received packet has errors. From yongari@FreeBSD Tested by myself and a number of end-users on i386/amd64/sparc64
2006-09-17revert revision 1.131, the code in question was later found to not ensureBrad Smith
the proper alignment requirement for the VLAN layer on strict alignment architectures. This would result in Jumbo's working fine as long as VLANs were not in use. If VLANs were in use and a packet comes in with a size of 2046 bytes or larger, it would be corrupted as it came up through the VLAN layer. Also check the hw max frame size, instead of the MTU, so the alignment fixup is done as appropriate. Fixes PR 5185. Tested by Rui DeSousa with macppc and myself with alpha/sparc64.
2006-08-22- Re-add the m_adj() back into em_get_buf(), but this time checkBrad Smith
the HW max frame size and only call m_adj() if the size is less than or equal to MCLBYTES - ETHER_ALIGN (2046). - Set the HW long packet enable bit on all adapters, even 82573 based adapters which are capable of Jumbo's. - Only do RX alignment fixup on adapters capable of Jumbo frames. ok jason@
