            Bug ID: 432
           Summary: Entering Non-numeric value for Setup hugepage
                    mappings,  dpdk-setup.sh still goes to create_mnt_huge
                    function and prints misleading info
           Product: DPDK
           Version: 20.02
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev at dpdk.org
          Reporter: m.bilal at emumba.com
  Target Milestone: ---

During creating hugepages by running dpdk-setup.sh script, if we give
Non-Numeric inputs, the dpdk-setup.sh still goes to the create_mnt_huge
function and prints the misleading information on terminal
The output of terminal is as follow

Reserving hugepages
sh: echo: I/O error
Creating /mnt/huge and mounting as hugetlbfs

Press enter to continue ...

Here "Creating /mnt/huge and mounting as hugetlbfs" is showing that hugepages
has been created, And actually hugepages were not created on system.
So this is giving the misleading information.

We can solve this issue by putting the Non-Numeric check on the input from the
user to create hugepages.
