* Converted the remainder of the NIC drivers to use the mii_attach()Marius Strobl2010-10-151-6/+7

* Make sure to not use stale ip/tcp header pointers. The ip/tcpPyun YongHyeon2010-10-141-0/+2
| | | | | | | | | | | | | | header parser uses m_pullup(9) to get access to mbuf chain. m_pullup(9) can allocate new mbuf chain and free old one if the space left in the mbuf chain is not enough to hold requested contiguous bytes. Previously drivers can use stale ip/tcp header pointer if m_pullup(9) returned new mbuf chain.

* Add the capability to read the complete contents of the NVRAM via sysctlDoug Ambrisko2010-10-062-0/+68
| | | | | | | | | | | | | | | | | | dev.bce.<unit>.nvram_dump Add the capability to write the complete contents of the NVRAM via sysctl dev.bce.<unit>.nvram_write These are only available if the kernel option BCE_DEBUG is enabled. The nvram_write sysctl also requires the kernel option BCE_NVRAM_WRITE_SUPPORT to be enabled. These are to be used at your own caution. Since the MAC addresses are stored in the NVRAM, if you dump one NIC and restore it on another NIC the destination NIC's MAC addresses will not be preserved. A tool can be made using these sysctl's to manage the on-chip firmware. Reviewed by: davidch, yongari Notes: svn path=/head/; revision=213489

| | | | | | | | | | | | | | | aligned on an 8 byte boundary. Prior to rev 1.36 this wasn't a problem because mbuf clusters tend be naturally aligned. The switch to using split buffers with the first buffer being the embedded data area of the mbuf has broken this assumption, at least on i386, causing a complete failure of RX functionality. Fix this for now by using a full cluster for the first RX buffer. A more sophisticated approach could be done with the old buffer scheme to realign the m_data pointer with m_adj(), but I'm also not clear on performance benefits of this old scheme or the performance implications of adding an m_adj() call to every allocation.
