Does this have to be global, could it just be static?

These memset's should be unnecessary. For example, dev_info
is always cleared already inside rte_eth_dev_info_get().

Unnecessary parenthesis hurt readability in this if statement.

Is the operator here should be || ?

Check is done for 'if either ret is not 0 or if it ret is 0 but not leaf' we skip leaf details print. If 'ret is 0 and is leaf' we skip continue to print leaf details.

IMO, using logical operator over bitwise operator is good here in if statement  . Like below.?

If (ret || (is_leaf == 0 ))

Ok thanks Reshma, but can you tell me how the earlier logic fails and runs slow compared to logical or?

Not about faster or slower. 

Logical operators are commonly used in decision making in C programming. 
Bitwise operators are used in C programming to perform bit-level operations.

Since , above if condition is for decision making here logical || operator will fit , so I am suggesting to use that. 

We  don't need to do any bitwise manipulation in if condition to make the decision, so bitwise | operator is not needed

Now I see, I was wondering the suggestion was for improvement for performance.

We can correct this in next patch set not v6 if this is only change for 'show tm'

It could be that compiler might optimize logical into bitwise operation
to avoid cost of conditional branch (if there are no side effects).

Checking with 'EXTRA_CFLAGS=-g' we get the code generated as 

"""
                        if ((ret) | (!is_leaf))
   9a512:       8b 85 28 fd ff ff       mov    eax,DWORD PTR [rbp-0x2d8]
   9a518:       85 c0                   test   eax,eax
   9a51a:       0f 94 c0                sete   al
   9a51d:       0f b6 c0                movzx  eax,al
   9a520:       0b 85 3c fd ff ff       or     eax,DWORD PTR [rbp-0x2c4]
   9a526:       85 c0                   test   eax,eax
   9a528:       75 74                   jne    9a59e <show_tm+0x73e>

Looks like the is_leaf is picked assembly 'test' is done then byte is set to 1 based on flags. This is then or with 'ret'. I think your observation is correct 'compiler is remapping to or'

If the operator is '|' what else except of 'OR' you expect it to be remapped?

Thanks for your correction. I have rerun with logical or

As mentioned earlier email I am ready to spin v6 with 'logical or'. But if there any other comments for show_tm it will be nice to accommodate to v6 rather than v7. So, can you please share if there any other comments for show_tm?

rte_mempool_obj_iter returns uint32_t,  so good to use  "ret" type to be uint32_t. So it will be in synch with below printf too.
