Do not use same variable for outer and inner loop in bonding test.
Since the loop is just freeing the resulting burst use bulk free.

The first argument of 'memcmp' function was equal to the second argument.
Therefore ASSERT would always be true.

The parenthesis were in the wrong place so that comparison
took precedence over assignment in handling IPv6 extension
headers.  Break up the loop condition to avoid the problem.

The event_dev_config initialization had duplicate assignments
to the same element. Change to use structure initialization
so that compiler will catch this type of bug.

The code was duplicating the same condition three times?
Reading the commit message, the intention was:

    Add unit tests to verify the zero len TLS records. Zero len packets are
    allowed when content type is app data while zero packet length with
    other content type (such as handshake) would result in an error.

There was useless loop when looking at the DMA address.
It looks like it was meant to skip whitespace before
calling strtok.

Good time to replace strtok with strtok_r as well.

The test loop was much shorter than desired because when
MAX_NUM is defined with out paren's the divide operator /
takes precedence over shift.

But when MAX_NUM is fixed, some tests take too long
and have to modified to avoid running over full N^2
space of 1<<20.

Note: this is a very old bug, goes back to 2013.

Do not use same variable for outer and inner loop in bonding test.
Since the loop is just freeing the resulting burst use bulk free.

The first argument of 'memcmp' function was equal to the second argument.
Therefore ASSERT would always be true.

The parenthesis were in the wrong place so that comparison
took precedence over assignment in handling IPv6 extension
headers.  Break up the loop condition to avoid the problem.

The code was duplicating the same condition three times?
Reading the commit message, the intention was:

    Add unit tests to verify the zero len TLS records. Zero len packets are
    allowed when content type is app data while zero packet length with
    other content type (such as handshake) would result in an error.

MAX_NUM is defined with out paren's the divide operator /
takes precedence over shift.

The expression for checking which lcore is enabled for 0-7
was wrong (missing case for 6).

The loop over policy actions will always exit when it sees
the flow end action, so the next check is redundant.

The order of comparison is wrong, and potentially allows
referencing past the array.

There was useless loop when looking at the DMA address.
It looks like it was meant to skip whitespace before
calling strtok.

Good time to replace strtok with strtok_r as well.
