Modified files:
sys/dev/pci : if_em.c
Log message:
Fix em_write_pci_cfg() and em_read_pci_cfg() to avoid unaligned access, and
make em_write_pci_cfg() do a proper read/modify/write cycle, to avoid changing
the neighbouring 16 bits. Also remove the comment in em_pci_set_mwi() and
em_pci_clear_mwi(); writting 0 to the status bits in the command/status word
is the right thing to do. Fixes a panic on sparc64 and other strict alignment
architectures.
