Validating the control action within tcf_ife_init() proved to fix the
above issue. A TDC selftest is added to verify the correct behavior.

selftests: tc-testing: fix parsing of ife type
In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format
specifier for the ife type changed from 0x%X to %#llX, causing systematic
failures in the following TDC test cases:
7682 - Create valid ife encode action with mark and pass control
ef47 - Create valid ife encode action with mark and pipe control
df43 - Create valid ife encode action with mark and continue control
e4cf - Create valid ife encode action with mark and drop control
ccba - Create valid ife encode action with mark and reclassify control
a1cf - Create valid ife encode action with mark and jump control
cb3d - Create valid ife encode action with mark value at 32-bit maximum
95ed - Create valid ife encode action with prio and pass control
aa17 - Create valid ife encode action with prio and pipe control
74c7 - Create valid ife encode action with prio and continue control
7a97 - Create valid ife encode action with prio and drop control
f66b - Create valid ife encode action with prio and reclassify control
3056 - Create valid ife encode action with prio and jump control
7dd3 - Create valid ife encode action with prio value at 32-bit maximum
05bb - Create valid ife encode action with tcindex and pass control
ce65 - Create valid ife encode action with tcindex and pipe control
09cd - Create valid ife encode action with tcindex and continue control
8eb5 - Create valid ife encode action with tcindex and continue control
451a - Create valid ife encode action with tcindex and drop control
d76c - Create valid ife encode action with tcindex and reclassify control
e731 - Create valid ife encode action with tcindex and jump control
b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum
2a9c - Create valid ife encode action with mac src parameter
cf5c - Create valid ife encode action with mac dst parameter
2353 - Create valid ife encode action with mac src and mac dst parameters
552c - Create valid ife encode action with mark and type parameters
0421 - Create valid ife encode action with prio and type parameters
4017 - Create valid ife encode action with tcindex and type parameters
fac3 - Create valid ife encode action with index at 32-bit maximnum
7c25 - Create valid ife decode action with pass control
dccb - Create valid ife decode action with pipe control
7bb9 - Create valid ife decode action with continue control
d9ad - Create valid ife decode action with drop control
219f - Create valid ife decode action with reclassify control
8f44 - Create valid ife decode action with jump control
b330 - Create ife encode action with cookie
Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal
to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass
both with old and new tc binaries.
While at it, fix a small typo in test case fac3 ('maximnum'->'maximum').

Validating the control action within tcf_ife_init() proved to fix the
above issue. A TDC selftest is added to verify the correct behavior.

selftests: tc-testing: fix parsing of ife type
In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format
specifier for the ife type changed from 0x%X to %#llX, causing systematic
failures in the following TDC test cases:
7682 - Create valid ife encode action with mark and pass control
ef47 - Create valid ife encode action with mark and pipe control
df43 - Create valid ife encode action with mark and continue control
e4cf - Create valid ife encode action with mark and drop control
ccba - Create valid ife encode action with mark and reclassify control
a1cf - Create valid ife encode action with mark and jump control
cb3d - Create valid ife encode action with mark value at 32-bit maximum
95ed - Create valid ife encode action with prio and pass control
aa17 - Create valid ife encode action with prio and pipe control
74c7 - Create valid ife encode action with prio and continue control
7a97 - Create valid ife encode action with prio and drop control
f66b - Create valid ife encode action with prio and reclassify control
3056 - Create valid ife encode action with prio and jump control
7dd3 - Create valid ife encode action with prio value at 32-bit maximum
05bb - Create valid ife encode action with tcindex and pass control
ce65 - Create valid ife encode action with tcindex and pipe control
09cd - Create valid ife encode action with tcindex and continue control
8eb5 - Create valid ife encode action with tcindex and continue control
451a - Create valid ife encode action with tcindex and drop control
d76c - Create valid ife encode action with tcindex and reclassify control
e731 - Create valid ife encode action with tcindex and jump control
b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum
2a9c - Create valid ife encode action with mac src parameter
cf5c - Create valid ife encode action with mac dst parameter
2353 - Create valid ife encode action with mac src and mac dst parameters
552c - Create valid ife encode action with mark and type parameters
0421 - Create valid ife encode action with prio and type parameters
4017 - Create valid ife encode action with tcindex and type parameters
fac3 - Create valid ife encode action with index at 32-bit maximnum
7c25 - Create valid ife decode action with pass control
dccb - Create valid ife decode action with pipe control
7bb9 - Create valid ife decode action with continue control
d9ad - Create valid ife decode action with drop control
219f - Create valid ife decode action with reclassify control
8f44 - Create valid ife decode action with jump control
b330 - Create ife encode action with cookie
Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal
to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass
both with old and new tc binaries.
While at it, fix a small typo in test case fac3 ('maximnum'->'maximum').
