X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83042955210aaee70b881240fe4f5e8409235308;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ipg: remove jumbo frame #ifdef from mtu

Remove JUMBO_FRAME #ifdef from dev->mtu setting in ipg_nic_open() so that we
can make IPG_TXFRAG_SIZE configurable.
