Subject: ixgbe: correct disable_rx_buff timeout
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=db76ad470e4577e4664af699d73ff7426791cde5;p=openwrt%2Fstaging%2Fblogic.git

ixgbe: correct disable_rx_buff timeout

The current value of the udelay timeout for ixgbe_disable_rx_buff is too
short. This causes the security path to not not be properly disabled during
the section that is meant to have it turned off. The end result causes a race
condition that results in RX issues.
