This patch removes two useless initialisations in the stmmac_rx and stmmac_tx functions. In the former, the count variable was reset twice and in the stmmac_tx we only need to increment the dirty pointer w/o setting the entry variable. v2: review the subject and comment that was not clear in my first version.
