Subject: f_phonet: fix skb truesize underestimation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=21dcda6083a0573686acabca39b3f92ba032d333;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

f_phonet: fix skb truesize underestimation

Now skb_add_rx_frag() has a truesize parameter, we can fix f_phonet to
properly account truesize of each fragment : a full page.
