selftests/bpf: Increase xdp data size for arm64 64K page size
With arm64 64K page size, the following 4 subtests failed:
#97/25 dynptr/test_probe_read_user_dynptr:FAIL
#97/26 dynptr/test_probe_read_kernel_dynptr:FAIL
#97/27 dynptr/test_probe_read_user_str_dynptr:FAIL
#97/28 dynptr/test_probe_read_kernel_str_dynptr:FAIL
These failures are due to function bpf_dynptr_check_off_len() in
include/linux/bpf.h where there is a test
if (len > size || offset > size - len)
return -E2BIG;
With 64K page size, the 'offset' is greater than 'size - len',
which caused the test failure.
For 64KB page size, this patch increased the xdp buffer size from 5000 to
90000. The above 4 test failures are fixed as 'size' value is increased.
But it introduced two new failures:
#97/4 dynptr/test_dynptr_copy_xdp:FAIL
#97/12 dynptr/test_dynptr_memset_xdp_chunks:FAIL
These two failures will be addressed in subsequent patches.
