Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this shifts into the sign bit. Instead use (1U << 31) which gets the expected result. Similar to the (1 << 31) case it is not defined to do (2 << 30). This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases. A similar change was made in OpenBSD.

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI

command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot. Submitted by: jhb Reviewed by: jfv, marius, achadd, achim MFC after: 1 day

Several cleanups and fixes to mxge:

2013-02-25T16:22:40Z

- Remove vestigial null pointer tests after malloc(..., M_WAITOK). - Remove vestigal qualhack union - Use strlcpy() instead of the error-prone strncpy() when parsing EEPROM and copying strings - Check the MAC address in the EEPROM strings more strictly. - Expand the macro MXGE_NEXT_STRING() at its only user. Due to a typo, the macro was very confusing. - Remove unnecessary buffer limit check. The buffer is double-NUL terminated per construction. PR: kern/176369 Submitted by: Christoph Mallon

Improvements for newer mxge nics:

2013-02-22T19:21:29Z

- Some mxge nics may store the serial number in the SN2 field of the EEPROM. These will also have an SN=0 field, so parse the SN2 field, and give it precedence. - Skip MXGEFW_CMD_UNALIGNED_TEST on mxge nics which do not require it. This saves roughly 10ms per port at device attach time. Sponsored by: Myricom MFC After: 7 days

Try harder to make mxge safe for all combinations of INET and INET6

2013-02-22T16:46:28Z

- Re-fix build by restoring local removed in r247151, but protected by #if defined(INET) || defined(INET6) so that the compile succeeds in the !(INET||INET6) case. - Protect call to in_pseudo() with an #ifdef INET, to allow a kernel to link with mxge when INET is not compiled in. - Also remove an errant (improperly commented) obsolete debugging printf Thanks to Glebius for pointing out the !(INET||INET6) build issue.
