[PATCH v2] lib/hash: Set the maximum reclamation size to user provided value

[PATCH v2] lib/hash: Set the maximum reclamation size to user provided value

[Abdullah Ömer Yamaç]

In the previous implementation, the maximum reclamation size was set
to RTE_HASH_RCU_DQ_RECLAIM_MAX and it was not configurable. This patch
uses the configuration argument to set the maximum reclamation size.

Hello,
I saw two comments, and the first one
" Please add:
stable@dpdk.org to the Cc list" then I added stable@dpdk.org to Cc. Would
you like me to add it to the commit?

Second one :
“Set the maximum reclamation size to user provided value”  I set this
comment to the header. I thought it was more meaningful in the header. If
you want also, I can insert it in the description part.

Do I miss something else?

I thought it needs to be added to the commit message as per contributing guidelines [1].

I meant that we should simplify the long commit message.
