Subject: [PATCH 0/2 net V3] net: vertexcom: mse102x: Fix mse102x_tx_work

This fixes two issue in the TX path of the Vertexcom MSE102x driver.

Initial version:
https://lore.kernel.org/netdev/20241022155242.33729-1-wahrenst@gmx.net/

Changes in V3:
- use a temporary variable to store the "original" skb len in
  patch 2 as suggested by Jakub Kicinski

Changes in V2:
- free the temporary skb in patch 1 in order to minimize changes
  as suggested by Jakub Kicinski
- add patch 2 to also fix the tx_bytes calculation

Stefan Wahren (2):
  net: vertexcom: mse102x: Fix possible double free of TX skb
  net: vertexcom: mse102x: Fix tx_bytes calculation
