tap: fix tap interface not working on Arm issue
The VPP code tries to set all userspace memory in the table via IOCTL to VHOST_SET_MEM_TABLE. But on aarch64, the userspace address range is larger (48 bits) than that on x86 (47 bits). Below is an segment from /proc/[vpp]/maps. fffb41200000-fffb43a00000 rw-s 00000000 00:0e 532232 /anon_hugepage (deleted) Instead of setting all userspace memory space to vhost-net, will only set the address space reserved by pmalloc module during initialization.
