From: Jacob Keller Date: Fri, 10 Feb 2017 07:44:27 +0000 (-0800) Subject: i40e: update comment explaining where FDIR buffers are freed X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a158aeaf5bb5b014240b360693751476aca7440b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git i40e: update comment explaining where FDIR buffers are freed The original comment implies that the only location where the raw_packet buffer will be freed is in i40e_clean_tx_ring() which is incorrect. In fact this isn't even the normal case. Update the comment explaining where the memory is freed.
