Subject: [PATCH net 3/4] ARM: socfpga_defconfig: Disable PHY time stamping by default.
Date: Wed, 20 Jan 2021 20:06:02 -0800 [thread overview]
Message-ID: <5ba5eaabd8dd610fa6b269fc746fd98421fe22a0.1611198584.git.richardcochran@gmail.com> (raw)
In-Reply-To: <cover.1611198584.git.richardcochran@gmail.com>
The NETWORK_PHY_TIMESTAMPING configuration option adds overhead into
the networking stack. When enabled, all transmitted and received
frames are subjected to extra tests to determine whether they just
might be PTP frames to be presented to esoteric PHY time stamping
drivers.
However, no System on Chip, least ways not the socfpga SoC, includes
such a PHY time stamping device. Disable the unneeded option by
default.
The diff includes a bit of extra churn caused by "make savedefconfig",
but the generated defconfig is now in the canonical form.
