Subject: net: hns3: refactor GL update function
Patch-mainline: v4.16-rc1
Git-commit: 8b1ff1ea2ccb09907d1af268e6450c061f477112
References: bsc#1104353 FATE#326415
The GL update function uses the max GL value between tx_int_gl and
rx_int_gl to set both new tx_int_gl and new rx_int_gl. Therefore, User
can not enable TX GL self-adaptive or RX GL self-adaptive individually.
This patch refactors the code to update the TX GL and the RX GL
separately, making user can enable TX GL self-adaptive or RX GL
self-adaptive individually.
