[PATCH net-next v2] i40e: remove fake support of rx-frames-irq

[PATCH net-next v2] i40e: remove fake support of rx-frames-irq

[Tony Nguyen]

From: Jason Xing <kernelxing@tencent.com>

Since we never support this feature for I40E driver, we don't have to
display the value when using 'ethtool -c eth0'.

Before this patch applied, the rx-frames-irq is 256 which is consistent
with tx-frames-irq. Apparently it could mislead users.

v2:
- use the correct params in i40e_ethtool.c file as suggested by Jakub.
