tap: Refactoring macvtap.c
macvtap module has code for tap/queue management and link management. This patch splits the code into macvtap_main.c for link management and tap.c for tap/queue management. Functionality in tap.c can be re-used for implementing tap on other virtual interfaces. Signed-off-by: Sainath Grandhi <sainath.grandhi@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ues. The queues are fixed by simply zeroing the memory before use. PIO errors from userspace will result in a SIGBUS being sent to the user process. The MEM errors form userspace will result in a SIGKILL and also cause the offending pages to be claimed so they are no longer used in future tasks. SIGKILL is used to ensure that the process does not try to coredump and result in an attempt to read the memory again from within kernel space. Although there is a HV call to scrub the memory (mem_scrub), there is no easy way to guarantee that the real memory address(es) are not used by other tasks. Clearing the error with mem_scrub would zero the memory and cause the other processes to proceed with bad data. The handling of other non-resumable errors remain unchanged and will cause a panic. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
